Yes, for the Last three days at about 11:00pm CST this has been happening... at least to the Texas area... it seems that the Game Masters Have posted in a prior forum thread on 24 Dec that the issue was resolved but apparently this is not the case... something is happening to server stability around that time (perhaps due to the load on servers???) it is rather strange due to the fact that it is not server wide... so some guildies are still online with no issues... if people could compare notes on ISP and locations it might help the GM's @ SWTOR
ISP: ATT
Location: Texas
has happened each night around 11:00PM cst for the last 3 days
