UK hosting provider Fasthosts suffered extended downtime on Monday night, which has been attributed to an electrical problem. Fasthosts, which was bought last year by 1&1 Internet, hosts more than 605,000 web sites, making it one of the UK's top three web hosting operations. Fasthosts told customers that the outage resulted from a problem in the electrical equipment that distributes power to servers. While there was no fire, a fire alarm was triggered, which in some scenarios can prompt staff to cut power to parts of the data center for safety reasons.
