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
