It was seen that twitter has been down yesterday , along with Facebook and LiveJournal due to the long DDoS attacks on their servers. Facebook some how did manage to get back up and provided users with their fast loading web pages even after the attack.

Twitter and LiveJournal went down hard, Facebook stayed mostly online but was clearly under strain

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. 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.
