Thursday US time, around midnight to 1:30am Australian Eastern Standard Time, Twitter, Facebook, Livejournal and a few other services were hit by a Distributed Denial of Service (DDos) attack.

It's now 1:35pm on a Melbourne Friday and Twitter is still showing some signs of being affected.  Facebook, Blogger and a few others have running without as much trouble, but it's making social media difficult today.

It seems the attacks have been targetting one person, a pro-Georgian blogger, across every service he uses.

It's also led to a new symbol of Twitter downtime, the Dead Twitter Bluebird, instead of a Fail Whale (courtesy of iStockPhoto.com)

At the same time, there's also a wave of scam/spam adding to the confusion.

UPDATE 4:40pm AEST:  Some conflicting reports on whether to do with pro-Georgian or pro-Abkhazia activist, also some conflicting theories on what exactly the attack was from a technical point-of-view.

UPDATE 6:00pm AEST:  It is now confirmed that the attack was indeed targetting one man.  Facebook security chief explains.
