The whale has a bug. Illustration: Twitter
Beginning Thursday morning, 140 characters started burning a hole in the virtual pockets of Twitter users the world over as the social network began experiencing intermittent outages.
A Twitter spokesperson told Wired via email: “Today’s outage is due to a cascaded bug in one of our infrastructure components.” What sort of snafu took down the network’s infrastructure wasn’t communicated.
A cascaded bug entails a situation where one item fails which causes another item to fail, and the fail trail continues like a trail of dominoes. It’s a cascading set of failures.
The irony of the situation is that Twitter hosted a Twitter Reliability Engineering Open House at the company’s new headquarters in San Francisco on Tuesday.
Even with Twitter’s extended outage today, the service can still claim a 99.6 percent uptime this month. Impressive for a service that used to experience outages whenever a large event, like an Apple liveblog or South by Southwest occurred.
The social network said that it would provide more information soon about the outage. Until then, Facebook and Google+ miss you; you should visit them.
Update: Twitter published a blog post about today’s outage. The social network continues to blame the interruption on a cascading bug and rolled Twitter back to the latest stable version of the service.
