Its a corrupt FileSystem so hopefully not hardware related.
The server main hard disk has a mirror backup so the data is being extracted from the second hard disk and then it will be restored and rebooted. This process will take some time before it can booted in recovery mode.
hmm... if it is only a hard disk fault, what takes so long to get the faulty disk replaced and the raid rebuilt? Been there, done that, offline time max half a day.
And even more mysterious: what killed the domain zone of amigaworld.net? None of the (tested) subdomains irc,de,se,se2,no,fr.amigaworld.net do exist anymore. No A record, no CNAME record. Don't tell us you were using the amigaworld.net server also as its own DNS and only switched to your hosters NS (ns.123-reg.co.uk) after the accident O.o
Well, it would be good if at least the domain zone could get fixed asap again to reinstate the IRC network at least.
