International Connectivity
Global IP Access KPNQWest – administration May 02 Interim arrangement with Worldcom in place early June 02 Accelerated procurement for Global IP transit in June 02 Sprint & Level3 both at 2.5 Gbit
Research Link Teleglobe ceased its voice and data services on 30th June
2002 Following tests on 25th June the research traffic to Abilene
and ESNET was transferred to the GEANT service
