How Twitter got disrupted - DDos attack

Twitter was shut down for hours on 6th August (Thursday morning) by what it described as a DDoS (denial-of-service) attack, silencing millions of Tweeters. This service disruption was the first major outage Twitter 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.

Just take a look below to understand how Twitter got disrupted !

A denial-of-service attack (DoS attack) or distributed denial-of-service attackDDoS attack) is an attempt to make a computer resource unavailable to its intended users.

Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or persons to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely.

Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root name-servers.

One common method of attack involves saturating the target (victim) machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. See figure below :

In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
It is interesting to note that, not only was the site down, but client applications that depend on the Twitter API could also not connect to the service, creating a complete Twitter blackout. According to June ComScore numbers Twitter has more than 44 million registered users and its user base has been growing rapidly for months as it becomes better known in the mainstream.
