CircleID

The Twitter micro-blogging service was knocked offline this morning for several hours as a result of a denial of service attack (DDoS). Twitter has confirmed and reported the attack in a post on its official blog earlier today: "We are defending against this [DDos] attack now and will continue to update our status blog as we continue to defend and later investigate." The company later reported that the service as been resumed but they are still continuing to defend against and recover from this attack. No further updates have been provided yet. Several sources are also reporting problems with Facebook today.
