The tables follow the same patterns to base level 160, so there weren't any problems with rAthena implementing it (following much discussion). The 175 update brings along a new set of skills that aren't yet implemented, so that change won't be added for a long time.
I'd like to congratulate whoever started the rumor, even I believed it for a while. xP
rAthena will be back up and running in a few days, and yes, we did indeed have backups.
Same issue as Fatalis/Zopokx on 2011-03-15. Invoking character has colored font displayed inches above their head; other characters either crash or can't view the text.
