*edit* 24/8/11 12.30am Systems are back online - TS back up, forums all working.. Jeff may need to restart his zombie server... enjoy folks
From about 4:30pm today the AGS host started rebooting by itself - faster and faster, with no events in the logs, then stopped responding altogether, so is offline.
I managed to get the databases for teamspeak, KOTF and AGS forums before it stopped responding... when I arrived home it had rebooted, so I immediately became suspicious after 8 months of solid uptime.
Backups began immediately after the third reboot - that's about 5 mins after I returned home for a quiet Friday night. - I continued reconnecting for about an hour in between random reboots (with the disk response/data seeming ok when the server was up) until they became more frequent until it eventually stayed offline.
I have managed to save a percentage of the (randomly rebooting) server so far - the databases & Theme folders for DR, KOTF & AGS, Jeff's zombie server, the teamspeak database and license key, the KOTF web.
The last backup of all of AGS I took, 16/12/10 (updated: original was from about a year ago)... wasn't really much different & the databases will have all the new posts, coz I definitely got them Things are looking up the more we back up - your help suggesting things I might miss will really help.
It may just be that the disk is OK, but we won't know that until the host responds. Mouldy has been up > 12 hours and headed to bed, and now so am I, so now we just cross our fingers and hope the disk is ok when we hear back from the host.
More info as it emerges.
