Honestly, it just seems like server numbers are down in general. I don't think my server (Saronia) even broke 2,000 during last weekend. The highest I saw during either prime NA or prime JP hours was around 1,780. Most of the time it was between 1,200-1,400.
I've wonder though, how is the lag? During prime-times and weekends (3,600 on Gysahl). I can't get anything done inside the adventurer's guild and/or the levescamp.
The lag still blows even when the numbers aren't all that high. I'm sure it's FAR worse for you though :(
I don't think there's ever been 3,600 people on at once on Saronia. Most I saw was 2,500 and that was right after the standard edition launched. An average "heavy population" evening for Saronia seems to be around 2,000-2,200. Edited, Oct 20th 2010 8:17am by Sasorex
