Just a note folks, the hpHosts server is in the process of being rebooted due to a major resource overload (it's actually taking over 15 mins just for it to shutdown ready for restart).
Apologies for the disruption.
Just an update, the server has been rebooted, and I've reconfigured it to try and allow for the extremely high traffic (around 3 times the amount of a few days ago), but sadly, it's not going too well, with the server constantly spending it's CPU time at around 80-90% usage. I've got a backup machine that I can use to try and lighten the load for now, so am going to get that setup and some of it spread over, as soon as I can.
Oks, I've setup the backup machine and moved over hpHosts (forums are still on the original server). I think I've remembered everything, but if you notice anything wrong, please do let me know.
