Telehouse felled by power outage

First time ever...since August

Telehouse - the supposedly bullet-proof hosting solution for ISPs - has suffered another embarrasing power outage, just over a month after the last one.

Many corporate websites and some ISP services were unavailable on Sunday after power failed at Telehouse North. We received emails from readers saying hundreds of corporate websites, several ADSL providers, and Nominet were all hit.

Many ISPs host at least some of their infrastructure at Telehouse because of its supposed ability to stay online.

Nominet systems administrator manager Ian Meikle told the Reg: "We were alerted on Sunday to problems with our machines. Our on-call engineer logged in, found the problems were caused by a power outage and took action to fix it. Within an hour or two we were back to normal."

A statement from Telehouse said:

Following a routine generator test within Telehouse North on Sunday 24 September 2006, a momentary interruption to critical power services occurred. At 12.46pm, the Uninterruptible Power Supply (UPS) system 'A' initiated an out of synchronisation transfer to internal bypass. A number of customers in the south side of the building are known to have been affected.

Upon receipt of the alarm, the UPS system 'A' was checked and immediately returned to normal operation from the bypass condition. Service for all affected customers was resumed as soon as possible although some delay will have occurred due to the need to reset certain equipment. Building checks commenced and local alarms and equipment were reset accordingly. Following the incident, Telehouse's Service Desk has provided additional support to affected customers to ensure that all services are resumed as quickly as possible.

Telehouse Europe will continue to investigate the cause of the UPS system error with the specialist manufacturer's maintenance team. Once the investigation is complete, Telehouse Europe will provide a full report to customers detailing the technical team's findings."

So, that's all right then.®
