I thought EVE was dying? (sarcasm)
According to a thread on EVE’s forums, backed up with a post from CCP Explorer, EVE achieved a new concurrent user record of “45,186 online pilots at 20:41 GMT”. No word yet on the level of lag the game was experiencing at the time, but since the thread is on page two without any significant complaints I’d say things were pretty reasonable.
Not too shabby, guys. :)
