                                PROXY STATEMENT
                                      FOR
                      2001 ANNUAL MEETING OF SHAREHOLDERS

                               ----------------

   This proxy statement contains information relating to the solicitation of
proxies by the board of directors of VIA NET.WORKS, Inc. (VIA, the Company, or
we) to be voted at the annual meeting of the shareholders of the Company to be
held at 8:30 a.m. E.D.T. on Wednesday, May 23, 2001, at the Hyatt Regency
Reston located at the Reston Town Center at 1800 Presidents Street, Reston,
Virginia, and at any postponements or adjournments of the meeting. These
materials were first mailed on or about April 20, 2001 to all shareholders
entitled to vote at the annual meeting.

                             PURPOSE OF THE MEETING

   At the annual meeting, the holders of our voting common stock shall consider
and vote on the matters noted in the attached Notice of Annual Meeting,
including the election of three Class I directors and any other matters as may
properly come before the shareholders. Our management will also provide a
report on VIA's performance during fiscal year 2000 and answer questions posed
by shareholders.

                         PROXIES AND VOTING PROCEDURES

   Only holders of our voting common stock of record as of the close of
business on April 5, 2001, the record date for the annual meeting, are entitled
to notice of, and to vote at, the annual meeting or any postponements or
adjournments of the meeting. We have two separate classes of common stock
outstanding, voting and non-voting. If you were a shareholder of the voting
common stock as of the close of business on April 5, 2001, you will be entitled
to one vote for each share of voting common stock you held as of the record
date. Our common stock is listed on Nasdaq National Market(R) and the Euronext
Amsterdam exchange under the symbol "VNWI". As of the record date, there were
54,074,899 shares of voting common stock issued and outstanding.

Solicitation of Proxies

   In addition to this solicitation, which we are conducting by mail, VIA and
its directors, officers and employees (who will receive no additional
compensation) may also solicit proxies in person, by telephone, telegram,
facsimile and other methods. VIA will pay all costs of the annual meeting and
of soliciting, printing and mailing proxies.

Revocability Of Proxies

   If you are unable to attend the annual meeting, we urge you to vote your
proxy. You may revoke your proxy at any time before the annual meeting or by
attending the annual meeting and voting in person. If you wish to revoke your
proxy, please send a written statement to the Secretary of the Company or send
another properly executed proxy dated as of a later date to be delivered at or
prior to the annual meeting.

Required Vote

   At the annual meeting, shareholders will be voting to elect Class I
directors to the board of directors of VIA. The three nominees who receive the
most affirmative votes will be elected as Class I directors. Under our Bylaws
and the Delaware General Corporation Law, shares represented by proxies that
reflect abstentions will

                                       1


be counted as shares that are present and entitled to vote for purposes of
determining the presence of a quorum. Accordingly, abstentions from the
election of directors will not affect the election of the candidates receiving
the most votes. With respect to all other proposals to come before the meeting,
abstentions will have the same effect as votes against such proposal. Shares
represented by brokers who are prohibited from exercising discretionary
authority because the beneficial owners of such shares have not provided voting
instructions (commonly referred to as "broker non-votes") will be counted as
present for determining the presence of a quorum, but will not be counted for
any purpose in determining whether a matter has been approved, except with
respect to proposals for which such shares are deemed to be entitled to vote,
in which case they will have the same effect as votes against such proposals.

Voting

   You may attend the annual meeting and vote in person. Or, as a registered
shareholder, you may vote your shares by proxy, by mail or by telephone. To
vote by mail, simply mark, sign and date your proxy card and return it in the
postage-paid envelope provided. You may vote by telephone 24 hours a day, 7
days a week by calling 1-800-293-8533 up until 6:00 p.m. on the day prior to
the annual meeting. These procedures may also be available to shareholders who
hold their shares through a broker, nominee, fiduciary or other custodian. The
enclosed proxy card contains further instructions for telephone voting. You
will need proof of ownership of VIA shares to be admitted into the annual
meeting. If you bring a proxy card, a recent statement from a securities broker
indicating your shareholding in VIA or a proxy from a securities broker if you
hold your VIA shares through a broker, you will be admitted to the annual
meeting.

   Shares represented by proxies in the form enclosed, if such proxies are
properly signed and returned and not revoked, and shares properly voted by
telephone, will be voted as specified. Where no specification is made on a
properly signed and returned proxy, the shares will be voted FOR the election
of all nominees for director. We know of no business other than the election of
directors to be transacted at the meeting. If other matters requiring a vote do
arise, the persons named in the Proxy intend to vote in accordance with their
judgment on such matters. To be voted, proxies must be filed with VIA's
Secretary prior to the time of voting.

                       ELECTION OF DIRECTORS--PROPOSAL 1

There are no family relationships among any of our directors or executive
officers.

Compensation of Directors

   Each of our independent directors who is not an employee of VIA or was not,
prior to our initial public offering, a board designee of one of our
shareholders, receives an annual fee of $5,000 for serving on our board, plus
$1,000 for each regularly scheduled meeting attended and $500 for each special
meeting and each committee meeting attended. In addition, each of these
directors, upon joining our board, received an option to purchase 100,000
shares of our common stock at an exercise price equal to the fair market value
of the stock on the date of grant. These options typically vest over three
years. In addition, prior to our initial public offering, independent directors
received the right, granted under our Key Employee Equity Plan described below,
to purchase up to 50,000 shares of our common stock at an exercise price equal
to the fair market value of the stock on the date of grant. Currently Messrs.
Battista, Breen and Puente are our only directors who have received this
compensation package. All of our directors are reimbursed for travel and other
expenses relating to attendance at meetings of the board of directors or
committees of the board of directors.

Our Confidentiality Policy and our Directors

   Because our directors may serve as executive officers or directors of
companies that compete with us for acquisition candidates, we have adopted a
policy on confidentiality to protect our confidential information and prevent
our directors from facing conflicts of interest that they may not be able to
resolve. Under this policy, our directors are not required to bring to our
attention any information about potential acquisitions of Internet services
providers and other related services providers of which they become aware
exclusively through their affiliations with, or membership on the boards of
directors of, other specified companies, and we do not consider this type of
opportunity to constitute a corporate opportunity of ours. Specifically, we
have entered into agreements under this policy with Edward D. Breen relating to
his relationship with Motorola, Inc. and with John G. Puente relating to his
relationship with Primus Telecommunications Group. In addition, under this
policy, our directors are required to maintain the confidentially of our
financial and operating information.

Board Committees and Meetings

   During the fiscal year ended December 31, 2000, our board of directors held
seven regularly scheduled meetings and three special meetings. All of the
directors attended or participated in more than 75% of the aggregate number of
the meetings of the board of directors and committees on which they served,
except William A. Johnston, who attended 65% of the aggregate number of board
meetings and finance committee meetings. The board has established standing
audit, compensation, finance and nominating committees. The membership of each
committee of the board is noted in the chart below.

                                       5





   Audit Committee. The audit committee recommends for approval and appointment
by our board of directors, and monitors the independence and performance of
VIA's independent auditors. The audit committee also assists the board by
monitoring the integrity of our financial statements and reviewing our
compliance with legal and regulatory requirements and overseeing our internal
control practices. This committee met on six occasions during the last fiscal
year.

   Compensation Committee. The compensation committee is responsible for
administering our Amended and Restated 1998 Stock Option and Restricted Stock
Plan and our Key Employee Equity Plan, establishing the compensation of our

                      REPORT OF THE COMPENSATION COMMITTEE

   The compensation committee of the board of directors has provided the
following report on executive compensation for fiscal year 2000. The
compensation committee members are Messrs. Puente, Battista and Goldman, all of
whom are non-employee directors.

Compensation Philosophy

   The compensation committee is responsible for administering our stock option
plans, including our Amended and Restated 1998 Stock Option and Restricted
Stock Plan and our Key Employee Equity Plan, establishing overall compensation
for our Chief Executive Officer and reviewing compensation policies for our
senior executive officers.

   VIA's compensation policies are intended to create appropriate incentives to
motivate our employees to achieve our corporate goals and to ensure our future
success. The compensation committee supports these policies by ensuring that
our executive officers receive competitive compensation packages that recognize
the contributions each executive makes to VIA's performance.

   VIA has structured its compensation packages for executive officers to
include three main components: base salary, performance bonus and stock option
grants. The compensation committee believes these three components will enable
and are necessary for the Company to attract and retain highly qualified
executive officers in the competitive technology industry.

   Base salary. The initial base salary for each executive officer is based on
negotiations with the individual taking into account market conditions, salary
history, and compensation levels of other executive officers with equivalent
responsibility within the Company. The base salary of each executive officer is
reviewed at his or her anniversary hire date for merit increases up to a
certain percentage of the base salary and for market adjustments. Merit
increases are determined primarily based upon each executive's contributions
towards the Company's success and his or her achievements within the
executive's functional area during the prior twelve month period. The
compensation committee reviews and approves recommendations for merit and
market adjustment increases made by VIA's Chief Executive Officer.

   Performance Bonus. All executive officers are eligible for an annual
performance bonus, generally, up to a specified percentage of their base
salary. The determination of performance bonuses for each executive officer,
other than the Chief Executive Officer, is based partly on achievement of
personal goals agreed upon between the executive and his or her supervisor and
partly upon specified corporate goals targeted to the executive's functional
responsibilities within the Company. The corporate goals component of the
performance bonus for each of VIA's senior executive officers, Messrs. Simmons
and Nydell and Ms. Graham, is based on the financial and business goals
established during the first quarter of the prior fiscal year. After the
conclusion of each fiscal year, the compensation committee reviews and reports
to the full board of directors the extent to which the corporate goals have
been met. The compensation committee also approves the performance bonuses to
be paid to VIA's senior executive officers based on the recommendations of
VIA's Chief Executive Officer (other than with respect to his own performance)
which takes into account the Company's success in meeting corporate goals and
his assessment of each executive's success in meeting personal goals. The
performance bonus amounts for fiscal years 2000, 1999 and 1998 are set forth in
the Summary Compensation Table in this proxy statement.

   Stock option grants. The compensation committee receives the recommendation
of the Chief Executive Officer for initial stock option grants for all
executive officers in connection with commencement of their employment.
Executive officers are typically eligible for additional grants of options in
recognition of extraordinary individual performance, promotion, and in
connection with a broad based general distribution of options to employees in
recognition of superior performance of the Company. The compensation committee
is responsible for approving all such subsequent grants based on the
recommendation of the Chief Executive Officer.

Chief Executive Officer Compensation

   Mr. D'Ottavio's annual base salary was established in 1998 upon his joining
the Company, based on negotiations with Mr. D'Ottavio, taking into account
competitive salary information reviewed by the Company. In May 2000, the
compensation committee increased his salary in recognition of his superior
achievements in leading VIA from a start-up company in 1998 with no revenues or
operations to a leading Internet services company with operations in major
commercial centers throughout Europe and Latin America, successfully raising
$188 million in two rounds of private financing, and bringing VIA public as a
listed company on the Nasdaq National Market(R) and the Euronext Amsterdam
exchange while raising net proceeds of $333 million. In formulating
Mr. D'Ottavio's 2000 increase, the compensation committee reviewed publicly
available information on compensation of other chief executive officers of
other Internet and technology companies to ensure that Mr. D'Ottavio would
receive a competitive and market-based compensation.

   Mr. D'Ottavio is also eligible for an annual bonus up to a maximum of 50% of
his base salary. The determination of the annual bonus for Mr. D'Ottavio is
based solely on the achievement by the Company of the corporate goals
established by the committee for each fiscal year to ensure that Mr.
D'Ottavio's compensation is aligned with achievement of the Company's goals.
The bonus award to Mr. D'Ottavio in 2000, 1999 and 1998 is noted in the Summary
Compensation Table in this proxy statement. The committee did not award him
stock options in fiscal year 2000, pending a review of options remaining
available in the overall option pool, but has done so in the first quarter of
2001 to recognize his contributions.

Option Grants in Last Fiscal Year

   The following table provides information relating to options to purchase
common stock we granted our named executive officers during the year ended
December 31, 2000. The percentages in the table below are based on the options
to purchase shares of our common stock we granted under our 1998 Stock Option
and Restricted Stock Plan in the year ended December 31, 2000. The options
described in the table below become exercisable over periods of from three to
four years and have a term of ten years. For periods prior to our initial
public offering, the market value per share presented in the table below has
been determined on a basis consistent with the method we used to price shares
of preferred stock we sold our investors. Potential realizable values are net
of exercise price before taxes and are based on the assumption that our common
stock appreciates at the annual rates shown, compounded annually, from the date
of grant until the expiration of the 10-year term. These numbers are calculated
based on the requirements of the Securities and Exchange Commission and do not
reflect our estimates of future stock price growth.

Option Exercises and Fiscal Year-End Option Values

   The following table presents summary information with respect to stock
options exercised by our named executive officers during the year ended
December 31, 2000 and owned by our named executive officers at December 31,
2000. For periods prior to our initial public offering, we have calculated the
value realized using a market value per share determined on a basis consistent
with the method we used to price shares of preferred stock we sold our
investors. We have calculated the value of unexercised in-the-money options
based on the closing price of the stock on the Nasdaq National Market(R) on
December 31, 2000 of $3.81 per share.

Stock Plans

   Key Employee Equity Plan. In 1998, we adopted the Key Employee Equity Plan
to attract and retain qualified officers, key employees, directors and other
persons at VIA and our operating companies by granting them the right to
purchase shares of our common stock. Typically, purchase rights under this plan
are fully vested on the date of the grant and expire two months from the date
of the grant unless earlier terminated.

   A total of 800,000 shares have been reserved for issuance under our Key
Employee Equity Plan, of which 585,483 have been issued and are currently
outstanding as of April 1, 2001. Currently, there are no outstanding purchase
rights under our Key Employee Equity Plan.

   Our compensation committee, which administers the Key Employee Equity Plan,
has full power and final authority to designate the grantees, to determine the
number of purchase rights awarded and to determine the terms and conditions
relating to the vesting, exercise, transfer or forfeiture of the grant,
including the exercise price. Upon termination of a grantee's employment or
other relationship with us, any unexercised purchase rights held by the grantee
terminate immediately.


                                       14


   1998 Stock Option and Restricted Stock Plan. We have adopted the Amended and
Restated 1998 Stock Option and Restricted Stock Plan, which allows us to issue
restricted shares of our common stock or options to purchase shares of our
common stock. The total number of shares of our common stock available for
issuance under the 1998 plan is 9,200,000, no more than 125,000 of which may be
issued in the form of restricted common stock. No person may be granted more
than 125,000 shares of restricted stock or options to purchase more than
1,000,000 shares of stock in any calendar year.

   The 1998 plan is administered by the compensation committee. Except as
described in the plan, our compensation committee determines the grantees, the
type of grant, number of shares subject to each grant, and the term, exercise
price, and vesting schedules for each grant. All of our employees are eligible
to participate under the 1998 plan. The maximum term of options granted under
the 1998 plan is ten years plus one month.

   Options to purchase 8,036,743 shares of common stock were issued and
outstanding under the 1998 plan as of April 1, 2001. All of these options are
subject to vesting requirements based on continued employment, typically
vesting over two to four years. Option agreements governing options granted to
VIA employees generally provide for the acceleration of the vesting period if
there is a change of control of VIA in which we are not the surviving company,
except if the surviving company assumes the obligations under existing option
grants, an equivalent and substitute option in stock in the surviving company
is provided, or VIA's board determines that the change of control will not
trigger accelerations of the options. The option agreements governing options
granted to Messrs. D'Ottavio, Simmons and Nydell and Ms. Graham provide,
without exception, for acceleration of the vesting period if there is a change
of control of VIA in which VIA is not the surviving company. Options granted
prior to our initial public offering on February 11, 2000 have an exercise
price equal to what the board determined the fair market value of the common
stock to be on the date of the grant. Options granted after the date of our
initial public offering have an exercise price equal to the closing price for
our stock on the Nasdaq National Market(R) on the last trading day immediately
prior to the date of grant.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

   No member of our compensation committee has been employed by or served as an
officer of VIA or our subsidiaries, or has had any relationship requiring
disclosure in "Related Transactions."

                              REPORTING COMPLIANCE
            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

   Section 16(a) of the Securities Exchange Act of 1934 requires our directors,
executive officers and certain shareholders to file reports with the SEC on
Forms 3, 4 and 5 for the purpose of reporting their ownership of and
transactions in our securities. Based on our review of Forms 3 and Forms 4 and
amendments thereto, filed during the year ended December 31, 2000 and Forms 5
and amendments thereto filed with respect to the year ended December 31, 2000,
and certain written representations, VIA does not believe that any of VIA's
directors, officers or beneficial owners of more than 10% of our common stock
failed to file a form or report a transaction on a timely basis.

                            AUDIT COMMITTEE CHARTER

   The audit committee of the board of directors shall assist the board in
monitoring (1) the integrity of the financial statements of the company, (2)
the company's compliance with legal and regulatory requirements and (3) the
independence and performance of the company's internal and external auditors.

   The membership of the audit committee shall consist of at least three
members of the board of directors, who shall serve at the pleasure of the board
of directors and be designated by the full board of directors, and who shall
meet the following criteria:

     1. Each member of the audit committee must be an independent director
  within the meaning of the applicable rules of any securities exchange on
  which the company's securities are traded or, if applicable, the Nasdaq
  National Market.

     2. Each member of the audit committee must be able to read and
  understand fundamental financial statements, including the company's
  balance sheet, income statement, and cash flow statement, or become able to
  do so within a reasonable period of time after his or her appointment to
  the audit committee.

     3. At least one member of the audit committee shall have past employment
  experience in finance or accounting, requisite professional certification
  in accounting, or other comparable experience or background which results
  in the individual's financial sophistication, including being or having
  been a chief executive officer, chief financial officer or other senior
  officer with financial oversight responsibilities.

   The audit committee shall make regular reports to the board.

   In meeting its responsibilities, the audit committee is expected to:

      1. Review and reassess the adequacy of the committee's charter annually
  and recommend any proposed changes to the board of directors for approval.

      2. Review the annual audited financial statements with management,
  including major issues regarding accounting and auditing principles and
  practices as well as the company's system of internal controls.

      3. Determine whether to recommend to the board of directors that the
  annual audited financial statements be included in the company's annual
  report on Form 10-K.

      4. Review with management and the company's independent auditors any
  significant financial reporting issues raised by them in connection with
  the preparation of the company's financial statements.

      5. Review proposed major changes to the company's auditing and
  accounting principles and practices that are brought to the attention of
  the audit committee by independent auditors, internal auditors or
  management.

      6. Recommend to the board of directors the independent auditors to be
  engaged.

      7. Confirm and assure the independence of the independent auditors by:

       a. Obtaining from the independent auditors a formal written
    statement delineating all relationships between the independent
    auditors and the company, consistent with Independence Standards Board
    Standard 1.

                                      A-1


       b. Actively engaging in a dialogue with the independent auditors
    with respect to any disclosed relationships or services that may impact
    the objectivity and independence of the independent auditors.

       c. Taking, or recommending that the full board of directors take,
    appropriate action to oversee the independence of the independent
    auditors.

      8. Review the performance of the independent auditors and, if so
  determined by the audit committee, recommend that the board replace the
  independent auditors.

      9. Review the appointment and replacement of the senior internal
  auditing executive, if any.

     10. Review any significant reports to management prepared by the
  internal auditing department, if any, and management's responses.

     11. Meet with the independent auditors prior to the audit to review the
  planning and staffing of the audit.

     12. Discuss with the independent auditors the matters required to be
  discussed by Statement on Auditing Standards No. 61 relating to the conduct
  of the audit.

     13. Review with the independent auditors any management letter provided
  by the auditors and management's response to that letter.

     14. Prepare the report required by the rules of the Securities and
  Exchange Commission to be included in the company's annual proxy statement.

     15. Review with the board as necessary in the audit committee's judgment
  the company's policies and procedures regarding compliance with applicable
  laws and regulations and with the company's code of conduct, if any.

     16. Review with counsel legal matters that are brought to the audit
  committee's attention and that may have a material impact on the financial
  statements, the company's compliance policies and material reports or
  inquiries received from regulatory bodies.

     17. Meet no less than once each fiscal quarter, and at least annually
  with the chief financial officer, the senior internal auditing executive,
  if any, and the independent auditor in separate executive sessions.

   The audit committee shall have the power to conduct or authorize
investigations into any matters within the committee's scope of
responsibilities. The committee shall be empowered to retain independent
counsel, accountants, or others to assist it in the conduct of any
investigation. The committee may ask members of management or others to attend
meetings and provide pertinent information as necessary.

   The company's independent auditors are ultimately accountable to the board
of directors of the company and to the audit committee, as representatives of
the shareholders of the company. The board of directors and the audit
committee, as representatives of the company's shareholders, have ultimate
authority and responsibility to select, evaluate, and, where appropriate,
replace the independent auditors.

   While the audit committee has the responsibilities and powers set forth in
this charter, it is not the duty of the audit committee to plan or conduct
audits or to determine that the company's financial statements are complete and
accurate and are in accordance with generally accepted accounting principles.
This is the responsibility of management and the independent auditors. Nor is
it the duty of the audit committee to conduct investigations, to resolve
disagreements, if any, between management and the independent auditors or to
assure compliance with laws and regulations and the company's code of conduct,
if any.
