Same problem starting today

Titanium
Comcast-Boston area

Im having the exact same issue tonight. 2 of my logins will not work, however a completely separate account has no problems. I have tried titanium and SoD and both aren't allowing me to log in, yet it allowed me to log in a completely separate account a few times, now that one isn't working as well. Im thinking it is definately account related. Sometimes It says logging in for a long time then times out, others it goes to a blank server screen. I even reset my router as per what the faq says about blank server screens and still not working. Using Att Dsl.

No problems the past few days (when most here were having their problems), played about 30 hours with at least a dozen logins as I was in and out of the house. Come today I've gotten nothing but the blank server screen. Have not yet seen the "Logging in" box previously mentioned, but out of 15-20 attempts to play today every one has ran into the blank server list. Titanium with Comcast.
