Twitter goes down for more than a hour

Twitter is notorious for going offline, but usually not for more than an hour. Today, however, the site was inaccessible — on the web and through Twitter clients — for just about one hour.

As of 10:20 a.m. Pacific time, the service and website are back online.

I noticed at around 9:00 am Pacific time that Twitter.com was showing a “could not connect” page. After checking TweetDeck, which was also down, I also checked www.downforeveryoneorjustme.com/twitter.com, which also confirmed the site is down.

A quick email to Twitter verified as the company provided some insight:

Users may be experiencing issues accessing Twitter. Our engineers are currently working to resolve the issue.

We will update as we learn more.

Update (10:45 Pacific time): Twitter has updated its status saying all issues have been resolved. Despite that, we’ve noticed that the site is still experiencing hiccups.

Update (12:45 Pacific time): Twitter has announced that the issues have been caused by “a cascaded bug in one of our infrastructure components.”
