Twitter Site Knocked Down In Hack Attack

SAN FRANCISCO (Reuters) -- Twitter, the popular Internet micro-blogging service, suffered an outage after a hacking incident.

A post on the Twitter blog by co-founder Biz Stone said that Twitter was the victim of a denial-of-service attack, a technique in which hackers overwhelm a website's servers with communications requests.

"We are defending against this attack now and will continue to update our status blog as we continue to defend and later investigate," read the posting.

Asked for comments on the outage in an e-mail, Twitter's Stone referred to the blog post.
