Tumblr Down

   The Tumblr platform is down and has been down all night. In fact, it's been down for nearly 16 hours as I'm posting this at 12:41PM EST. Try to access any Tumblr-hosted site and you'll be greeted with the following message:

http://tumblr.com/

We'll be back shortly.

We're working quickly to recover from an issue in one of our database clusters.  We're incredibly sorry for the inconvenience.

Update at 2:38PM EST: Still down.
Update at 3:54PM EST: Still down, which makes it 19 hours and counting.
Update at 5:15PM EST: 20 hours and not a peep. Can we make it to 24 hours?
Update at 6:35PM EST: 21 hours and Tumblr's own site is online. One of my blogs there is up but the archive is unaccessible. According to a recent Tumblr tweet, full service should be restored soon.
