If any of you have followed updates on Twitter from @techhaven there was an incident at the data centre where the THN server is hosted. Something happened that caused the server to get very hot, and eventually one of the disks in the RAID1 array failed.
I wish I could tell you what happened exactly but the data centre hasn't given me many details - except that the air con went offline, and the emergency services were involved. You can speculate all you like what that means. What I do know is the disks reached temperatures of around 63C at one point.
So while a new replacement disk is obtained and fitted, the THN will remain offline. I will look at temporarily hosting the THN on a VPS solution in the next few days. If anyone knows of any decent UK/EU VPS providers please chuck a link in this thread.
Edit: P.S. Forgot to mention a important point. All data and files are all backed up and safe.
