What 'service'?....
Probably just you....
Just tried it today also, and confirmed not working also. I have a link direct to my personal page that reports "Service Unavailable" and if I go to the WC mainpage and try to login it says: "Invalid Email Address or Password".
[Edit] Just asked the site to send me my password (which arrived correct as I remembered it) and it still won't let me log in.
[Edit#2] Suddenly the site recognises my login, but still can't get to my personal pages...
