Having some trouble with your blog? On Thursday, Wordpress.com, a major blogging site, was hit with a denial of service attack. Graham Cluey he internet security firm, Sophos, posted a picture of an e-mail he received from Wordpress on his Twitter account.
The e-mail says that the site is suffering an “extremely large” denial of service attack that it was having trouble fighting off. Shortly after noon, Wordpress tweeted that the site was experiencing “sporadic slowness.”
Sporadic slowness is back -- we're battling a non-trivial DDoS attack and will update as soon as it's mitigated.
Several prominent blogs, including TechCrunch,, recieved an e-mail from WordPress founder Matt Mullenweg saying:
There’s an ongoing DDoS attack that was large enough to impact all three of our datacenters in Chicago, San Antonio, and Dallas — it’s currently been neutralized but it’s possible it could flare up again later, which we’re taking proactive steps to implement.
This is the largest and most sustained attack we’ve seen in our 6 year history. We suspect it may have been politically motivated against one of our non-English blogs but we’re still investigating and have no definitive evidence yet.
Service at the site seems to working fine at the moment, but, as Mullenweg said, it is possible it could flare up again.
