NEWS RELEASE FOR IMMEDIATE RELEASE COVISTA COMMUNICATIONS, INC. REACTIVATES NEW YORK CITY SWITCHING FACILITY; PROVIDES EMERGENCY TELECOMMUNICATIONS SERVICES TO AID LOWER MANHATTAN RELIEF EFFORTS LITTLE FALLS, N.J. September 27, 2001 Covista Communications, Inc. (NASDAQ: CVST) announced today that it has reactivated its New York City switching facility that had been temporarily disabled when the World Trade Center was attacked on September 11. With the implementation of a completely reconstructed electric power grid by the local utility provider, full electric power has been restored to the area, and service is being restored to all Covista customers who had experienced outages during the last two weeks. John Leach, Covista's President and Chief Executive Officer, praised the efforts of all those who had helped to bring the facility back to full operation. "This has been a remarkable partnership in the face of unimaginably difficult circumstances. The technical support staff at Alcatel who manufactured and installed our switch, the building management, the City of New York, which also is a major tenant in the building, the power company, and our own engineering and operations staff have worked tirelessly together. While we still are experiencing the loss of certain facilities operated by other carriers with whom we interconnect, we anticipate that most of our customers who have been affected by this outage will be turned back up within the next 24 hours, and we are looking forward to the early restoration of full service for everyone in the region." Covista also announced that it has been providing emergency telecommunications services to the Business Improvement District which services the World Trade Center area, commonly known as the Downtown Alliance. Mr. Leach added, "We were able to take advantage of the fact that our facilities are in the same building, to run a direct cable connection from our switch to their offices. We are gratified to be able to assist the ongoing relief effort by providing essential services under circumstances in which they would not otherwise have been available."
