Datanet, the UK business ISP, suffered a power outage in of its server racks this morning which crocked its customers' internet access and email for most of the day.
MD Conlema McCallan said the failure affected the power distribution circuit, rendering the rack's uninterruptible power supply useless. The glitch has affected the "vast majority" of Datanet's customers, he said.
When the servers were rebooted errors were raised, so engineers at the Heathrow site, operated by IX Europe, decided to rebuild the filesystem from scratch rather than apply a "quick fix".
The aim is to ensure that no queued email is lost, which so far seems to be the case, McCallan said. Email should start coming through in the next one to two hours.
Datanet operates service level agreements that have been breached by the outage. ®
