If you had problems accessing this blog yesterday and early this morning, you are not alone.
WordPress is this blog’s generous wonderful host. Yesterday (and early this morning too), WordPress came under a huge and potentially politically-motivated Distributed Denial-of-Service attack. The attack is the biggest in the 6-year history of WordPress.
WordPress stung in massive Distributed Denial of Service attack

“The size of the attack is multiple Gigabits per second and tens of millions of packets per second,” outlined WordPress in an official alert email to its user base.
Although engineers “are working to mitigate the attack” the mail warned that its extreme size was “proving rather difficult” to deal with.
As a result, the 18 million blogs regularly relying on WordPress for online hosting were left experiencing problematic connectivity issues with the service.
In terms of impact, WordPress founder Matt Mullenweg said data centres in Chicago, Dallas and San Antonio suffered the brunt of the attack, which is described as the biggest to hit the hosting company in its six-year history.
In offering an opinion with regard to a reason behind the attack, Mullenweg told CNET that it “may have been politically motivated against one of our non-English blogs.”
As of Thursday afternoon, the DDoS attack had reportedly been quashed, but users have been advised that it could make an unexpected return at a later time.
WordPress parent company Automattic has since launched an official investigation into the matter.
