Twitter, Facebook and LiveJournal spent yesterday battling a DDOS attack that started around 6 am California time. Twitter and LiveJournal went down hard, Facebook stayed mostly online but was clearly under strain. CNET reports that a single individual’s accounts on the services may have been the primary target.
Now, nearly 24 hours later, Facebook and LiveJournal appear to be performing normally. But Twitter is down completely and has been for the last few hours.
As of 4 pm Twitter was saying things were looking better: “Site latency has continued to improve.” But for most users, all third party services have been completely unusable for the last 20 hours or so (Tweetdeck, Seesmic, Power Twitter, etc..), bringing down the entire Twitter ecosystem. The Twitter.com site itself hasn’t been reliable either.
The Twitter status blog has been silent since that 4:14 update.
