A number of companies including telcos and ISPs suffered were hit Wednesday after a power failure at colocation outfit Telehouse Europe.
The problem which hit the company's Docklands site in London has now been resolved although an investigation into the cause has been launched.
In a statement the company said: "At 08:05 on 29th June 2005 Telehouse Europe experienced a hardware failure on UPS system 'D'. This failure affected the forth floor of Telehouse Europe's East building.
"The power was restored at 08:50 via the emergency power generators and local equipment then reset.
"Telehouse Europe are currently investigating the cause of the hardware failure. Telehouse will provide an update following the investigation."
In March colocation rival Redbus apologised after a power failure at its Harbour Exchange facility in London caused loss of service to some of its customers. ®
