Extreme outage for Internode’s Adelaide subscribers

A "complex technical problem" with Internode's DSLAMs yesterday caused a 22-hour broadband outage for some customers in Adelaide.

Customers on Internode's 'Extreme' ADSL2+ services reported authentication issues late Monday night.

Engineers attempted to address the issue by rebooting DSLAMs in various metropolitan exchanges.

However, the reboot failed to resolve the issue, which had spread to DSLAMs in 16 of Internode's 36 exchanges in metropolitan Adelaide by 8am yesterday.

The issue was said to have occurred within the management and configuration applications of Internode's DSLAM equipment, which was provided by Ericsson.

Software upgrades were applied to all affected DSLAMs yesterday afternoon and appeared to resolve the issue, although Internode has been carefully monitoring the exchanges for any related issues since.

"Internode is continuing to monitor the performance of these DSLAMs to ensure that everything is working fine," an Internode spokesman told iTnews.

"[Internode] will undertake a review of the precise cause of the problem and identify how such issues can be avoided in future."

Although the outage affected less than ten percent of Internode's customers in the Adelaide area, "Internode recognises that lack of broadband service has a serious impact on anyone affected and apologises for any inconvenience that occurred," he said.

Services were restored by 8pm yesterday. Customers with ongoing issues were advised to reboot their modems.

Internode engineers provided regular updates to those affected by the issue.

Ericsson, which had been working with Internode to resolve the issue, declined to comment.
