When I try to login I get a "Connection Lost" ..Server returned HTTP response code: 503 for URL........message. This is happening more and more freqently on weekends.
The multiplayer session servers are down. This means you aren't able to log into any servers. SP works fine.
Considering the only thing Mojang has to keep working is the login and session servers, they sure do seem to be down a lot..
Still not working, for me anyway. agreed its a Mojang problem (agai)... Time to play another game while waiting.
