Update #2: And it's back up! Your day can go on like usual, we can breathe normally again now that Reddit is back!
Update: According to @redditstatus on Twitter, there was some scheduled maintenance for four hours ago, with a tweet that said: "We'll be performing some database maintenance that will require the site to be in read only mode for May 11, 22:00 - 22:30 PDT". The next tweet which was from around 52 minutes ago read: "Investigating: We're investigating a database master that's gone unavailable".

Sites like Reddit don't just run from a single server in an ISP, they have many thousands of servers with companies like Amazon so that this type of thing never happens.
We'll report back when we find out more.
