In Champions Online, I can login now, but when it goes to "Retrieving list of characters..." it immediately bumps to "The server is closed for maintenance at this time." So I'm guessing the server is coming back up now and they're running diagnostics?
Give 'em a break. They probably had to roll the one guy who knows how the archaic, 13-year-old server works out of bed and get him sobered up enough to stop speaking gibberish.
"We are aware of the issue affecting servers and are currently investigating." My guess is that one of the three people who actually work for the company got drunk and tripped over a power cord for the shared server.
Looks like all of ARC has gone down - was playing Champions Online and got booted, haven't been able to hit up the support there or for STO and neither of the login splash screens load up.
