Wordpress crash hits 10 million blogs

A router snafu knocked 10 million blogs hosted by Wordpress.com off the web for almost two hours last night, the company's worst downtime in four years.

The crash affected both free and premium blogs and caused about 5.5 million potential pages views to fail, although there was no word about any corresponding loss of revenue.

The company's “VIP” customers include official blogs for CNN, Flickr and Top Gear, as well as high-traffic tech sites such as GigaOM and Techcrunch, which had switched to Wordpress just a couple of weeks ago after its previous host was hacked.

“We are still gathering details, but it appears an unscheduled change to a core router by one of our datacenter providers messed up our network in a way we haven’t experienced before, and broke the site,” Wordpress CEO Matt Mullenweg eventually blogged.

The problem also caused the company's failover systems to fail, he admitted. Despite the outage, the vast majority of user comments on Mullenweg's post appeared to be very supportive.
