Last time something like this happened there was a flood of KGS-players migrating to CyberORO or IGS. Of course one could also take this as an opportunity to study some more 😉
UPDATE – KGS is back up. The cause of the crash was described by wms as follows:
FYI – The cause was the disk of games filling up. I thought I had some room left, but I forgot that Linux refuses to let non-root users fill up the last 5% of the disk, so the server crashed when it couldn’t save games. I transferred the games from 2004 to another disk; this took about 5 hours. I can’t believe that “cp -rp” could run that slow on an otherwise-idle system, even if it is copying millions of small files. I suspect that the server has too strong a journalling mode enabled or something like that, but there you are. Once 2004 was transferred to another disk, I was able to delete it and restart the server. Should be safe until the next time the disk fills up.
