Error: java.io.IOException: Server returned HTTP response code: 503 for URL: http://session.minecraft.net/g.....?user=your IGN here]&sessionId=[session ID here]&serverId=[server ID here]
I get this when I attempt to connect to any Minecraft server. I believe it's an issue with their authentication servers. I've been told an error 503 is when the server is unavailable due to an overload or is running in maintenance mode.
Hopefully this will be resolved as soon as possible - just posting this to let anyone else with the same error know they're not alone.

Hi Guys,We are aware of the security issues involved with the Minecraft authorization servers and are currently working to fix it.
Right now the authorization servers have been taken offline and will be down until further notice. The Mojangstas are working hard to make sure we get everything back to perfect working order.
We’ll keep you updated as we have a more clear timeline. We really are sorry about this and are working as fast as we can!
Happy Sunday

Xlson: We have taken down the session servers to make it impossible to login to minecraft servers while we fix the security problems.
