Telecom ATM crash hits Voyager, Ihug

A major failure of Telecom's ATM network yesterday hit Voyager and Ihug and interrupted the delivery of thousands of emails.

A major failure of Telecom's ATM network yesterday hit Voyager and Ihug and interrupted the delivery of email between many ISPs.

It also affected hundreds of medium to large businesses which use frame relay circuits. Telecom customers began reporting problems with national connectivity via the ATM network around 10pm on Sunday night.

The fault at the Mayoral Drive Exchange apparently became more serious when a number of ATM circuits went down for about 30 minutes shortly after midnight. That outage caused 11 frame relay cards to fail.

The failure hit Voyager, which lost its IPNet dial-up service and was forced to divert its 0873 IPNet number to other equipment within its network. The company reported that some users were able to log on but warned there could be delays because of overloading. It reported the issue had been resolved at 2.10pm yesterday.

Ihug suffered network failures affecting most of its domestic circuits, including DDS links to business customers and all dial-up POPs except Auckland, Hamilton, Wellington Whangarei and Invercargill. Circuits were restored through the day, with Tauranga, Pukekohe, Hibiscus Coast and most DDS customer circuits among the last to be repaired.

Ihug declared that all its internal and external circuits were operating again at 9.10pm. A backlog of thousands of undeliverable emails to other New Zealand ISPs, including Xtra, was cleared shortly afterwards.

There were reports of email interruptions at companies in the main centres.
