Further attacks on WordPress under investigation
Following a massive attack on WordPress.com on 3 March, WordPress was hit by a second attack in the early hours of the morning of 4 March. Apparently there was some speculation that the attacks might be connected to the current unrest in the Middle East, but investigation now appears to show that these attacks originated in China, with some traffic from Korea and Japan.
The Automattic status page which displays the operating status for WordPress and other services still shows the two outages. A note on the second attack states, "Unfortunately, the DDoS attack from yesterday returned in a different form this morning and affected sitewide performance,The good news is that we were able to mitigate it quickly and performance returned to normal around 11:15 UTC. We are continuing to monitor the situation closely."
WordPress founder Matt Mullenweg commented to TechCrunch that one of the targeted sites was a Chinese-language site that was also blocked on Baidu, leading to the initial assumption that the attack was political. Later he said that closer investigation showed it more likely to have been business related, although there has been no response from the site's owner.
