Internet problem
The internet routing problems which made it almost impossible to contact our server and much else in Texas were resolved after about an hour and the server was again contactable at about 12.00 midnight GMT.
Everything seems to be ok this morning.
It was exteremely unfortunate that at the time of the outage Yann and I were trying to fix problems caused by a misconfiguration by the Hostgator support staff which was affecting a number of domains. I think this is now all done, but please contact me if you still have problems with your website.
