If anyone noticed the severe connectivity issues affecting this site yesterday, here’s the reason:
Blog host WordPress.com was the target of a distributed denial-of-service (DDoS) attack earlier today described by the company as the largest in its history.
As a result, a number of blogs–including those that are a part of WordPress’ VIP service–suffered connectivity issues. That includes the Financial Post, the National Post, TechCrunch, along with the service’s nearly 18 million hosted blogs.
According to a post by Automattic employee Sara Rosso on the company’s VIP Lobby (which had been down at the time of the attacks, though was archived by Graham Cluley over at Naked Security), the size of the attack reached “multiple Gigabits per second and tens of millions of packets per second.” Rosso had also said putting a stop to the attack was “proving rather difficult.”
