Womp womp.

What's your first source for news of popular Internet service dealing with downtime? That's right: irate users complaining on Twitter. But where does Twitter turn, when that stream of 140-character updates is cut off and there's no way to communicate that they are on it? As the National Post points out, they turn to Tumblr.

That's right: When you need to know whether it's your Internet connection, your crappy computer, or Twitter's own servers, the best place to get an answer is status.twitter.com, which is powered by Tumblr.

As the Post points out, hundreds of people attempted to tweet the update.

When Tumblr goes down, on the other hand, you'll know it from the horrified screeches of millions of teenage girls.
