During the early hours of Monday, Fasthosts' automatic back-up systems were activated and its newly refitted diesel turbines deployed after local power supply outages occurred. Fasthosts' data center uses an advanced APC X UPS system which provides uninterruptible power to all servers. When the mains electricity failed, the power supply was switched instantly, without interruption, to N+1 diesel generators which are capable of running the data center for weeks. As a result, thousands of servers and some 700,000 hosted domains remained online and unaffected.

Since the early hours of Tuesday morning, the local mains power has been reinstated to the normal level. A minor amount of servers, which comprises only 0.05 percent of users served by the Gloucester, UK data center, experienced a reduction in service as a result of a system reset. These servers have been returned to regular service now.

"We are satisfied that our disaster recovery plan worked well and were able to uphold our uptime promise to our customers," says Mark Jeffries, CTO of Fasthosts Internet. "I am hugely proud of our staff for their commitment during the difficult trading conditions."

Fasthosts announced earlier this month the results of its recent survey which shows that 78 percent of British consumers have been disappointed by a slow response to a customer service email enquiry.
