As you’ve probably heard, WordPress.com had a major network issue today. Fortunately, Akismet was not affected — all Akismet API services were operating at full capacity. (Some tweets and blogs incorrectly reported that Akismet was down too.)
We are of course monitoring closely for signs of any aftershocks. As always, if you have any Akismet problems or questions, please contact our support.
Details of the WordPress.com downtime are posted in this announcement on the WordPress.com blog.
