Denial-of-Service ****** Knocks Twitter and other sites Offline. (Updated)

Twitter was shut down for hours Thursday morning by what it described as an “ongoing” denial-of-service ******, silencing millions of Tweeters. It was the first major outage the service has suffered in months and possibly the first ever due to sabotage. The outage appeared to begin mid-morning, EST, and affected users around the world. After about three hours, the service was coming back online in fits and starts (updated).

What is a denial of service ******?

Yesterday's technical assault on Twitter and other social-networking websites, such as Facebook and Livejournal, is known as a distributed denial of service ******. This technique uses a network of tens of thousands of compromised computers, known as a "botnet", to flood a website's servers with page view requests, leaving legitimate traffic unable to get through. This huge amount of connection requests can quickly overwhelm a server and, in some cases, cause an entire website to crash.
