GoDaddy.com says a Web hosting outage that involved thousands and possibly millions of websites was due to internal problems, not an attack by hackers.

The outage lasted for about four hours Monday and affected mainly small-business sites.

GoDaddy.com hosts more than 5 million websites.

In a statement Tuesday, the Scottsdale, Ariz., company says "internal network events" fouled up its routers, which direct data traffic.

On Monday, a Twitter feed that claimed to be affiliated with the "Anonymous" hacker group said it was behind the outage and drewwidespread ire and attention.

Another Twitter account, known to be associated with Anonymous, suggested the first one was just taking advantage of an outage it had nothing to do with.
