It looks like minecraft is currently not working for most people. Both the offline and online clients are AWOL, and Notch, the big man on campus for Minecraft, is currently on vacation at his mom's house. Lol.
Just as I was about to start making a few resetting boosters for you guys. This is not cool.
Stay tuned to these channels for updates. Hopefully Notch will get his fill of mom's home cooking and get back to the office soon!
