Multiplayer Sessions are down

[Missters]

oh.. but there are other people online? atleast it says people are on... Why cant i get in then?

[Winniedoxie]

The people online are the ones who stayed online when the minecraft sessions failed. So no new people can log in but the people who stayed can continue playing unless they log out.

Yeah, lots of people were trying out the new Irc so not many people were online.

Well, I saw Smp opticraft count was at 11 now 30. :/

Then does that mean there up?

And it looks like the services went back down. One of the services is probably in a state of instability upon rebooting

Even though I could get on when they were down lol
