Yes, we know that you know that Twitter was down for a little while earlier today, we just wanted you to know what caused it. Too bad we can’t definitively tell you!

According to Apica, Twitter’s homepage began showing errors at 6:33 a.m. PST.

But why did today’s Twitter outage happen? Well, according to @twittercomms it was a “cascaded bug.”

While you can still access the site and make updates (which will appear, but can only be seen by you), that’s all you’ve been able to do on Twitter for the past 22 minutes. It appears the site started experiencing problems around 3:26pm GMT.

This used to be a fairly regular occurrence but it’s the first time it’s happened in this manner for a while. (Recent outages have been more terminal, with the network being completely inaccessible.)

Hopefully it won’t be too long before it’s back up and running again.

UPDATE: I’ve also noted my following and followers counts keep resetting to zero. Also, if you visit select profiles, they seem to be updating, but it’s not coming through within your timeline.

1630 GMT: Curiously, Facebook appears to be glitching as well. I’m having to post updates twice before they ‘stick’. This can only mean one thing – alien invasion. They’re using our social networks against us!

1900 GMT: Replies appear to be working and appearing in your mentions folder. Reply somebody and if they reply you back, you should see it. (Thanks to @trniii for the tip.) You can also see updates by visiting profiles directly, or by using Twitter search.

Meantime, Twitter has updated their status blog with a report on the problem and is looking into it.
