WordPress blog service down: Huge DDoS attack

WordPress: blogging service has been extensively hit by denial of service attack. Large no of blogs were unavailable for most of the time on Thursday.
WordPress currently hosts 30 million publishers and serves 10% of all websites in the world and have about 300 million unique visitors monthly.
...
Automattic and WordPress founder Matt Mullenweg tells us that this is the largest attack WordPress.com has ever seen, and is likely to be politically motivated.

The amount of junk data that was thrown at the company's servers while the DDoS ... attack was ongoing made it hard to defend against it using standard countermeasures.

Although it is smaller than Google-owned Blogger and other hosts, but it is a crucial platform for large amount of Web’s population ( 8.5% of websites)..
WordPress which is used by over 13 percent of the 1,000,000 biggest websites, was hit today by an "extremely large" distributed denial-of-service (DDoS) attack.

The size of the attack was multiple Gigabits per second and tens of millions of packets per second large enough to impact all three of the company's datacenters in Chicago, San Antonio, and Dallas.
DDoS attacks typically involve botnets of compromised computers around the world, bombarding a site with traffic - effectively "clogging it up" and preventing legitimate users from accessing its content.
It's unclear what has motivated the DDoS attack, but ... WordPress has just notified that their systems are back to normal.
As of now, the attacker has not been identified but is believed to be a politically motivated assault. The recent unrest in the Middle East has led to a greater use of Blogging to inform the world and fellow protesters of the various revolutions taking place. Pro-Government supporters could have targeted non-english Blogs in an effort to silence them.
