Updated Announcement Regarding Service Disruptions Caused by Taiwan Earthquake

NTT Communications (NTT Com) has confirmed that some customers have been unable to use data transmission (IPLC, IP-VPN, frame-relay, ATM), Internet connection, and optional international telephone services as of 9:30 p.m. (Japan standard time), December 26, 2006. This service disruption was caused by damage to undersea cables from an earthquake off Taiwan’s southwestern coast on December 26.

NTT Com has mostly restored these services through measures such as temporary rerouting and working with other carriers. Full restoration of services is expected by mid-January 2007, and the undersea cables should be repaired by the end of February 2007.

Status of services as of 3 p.m., January 10, 2007:
Data transmission services for corporate users
-IPLC: 145 lines have been restored (146 lines originally affected)
-Frame-relay: All lines were restored by December 28, 2006 (18 lines originally affected)
-IP-VPN: All lines were restored by December 27, 2006 (71 lines originally affected)
-ATM: All lines were restored by December 30, 2006 (14 lines originally affected)

Internet connection service
-Global IP network service: IP backbones in Asia have mostly been restored, yet delays may occur due to congestion

International telephone services
-All optional international telephone services (toll-free service and prepaid telephone card service) have been restored for calls to Japan from the nine countries and areas where problems were reported: Australia, Hong Kong, Indonesia, Malaysia, Singapore, Sri Lanka, Taiwan, Thailand, and Vietnam.
-Regular international telephone services have been unaffected by rerouting, but it might be difficult to get through.

We apologize for any inconvenience this may have caused and will do our best to resolve all problems as soon as possible.
