Not entirely sure why at the moment, but both temerc.com and fluidhosting.com (temerc.com hosting company) are down at present.
I'm still looking into why, and due to a very annoying difference in time (i.e. their being several hours behind us folk in the UK), is making contacting them a little difficult. I have ruled out an issue with DNS as they're resolving absolutely fine, and trying to load the site via IP instead of hostname, yields the same results.
Looking at a tracert result indicates the problem is inside the FluidHosting network as there's no timeouts or such.
If you've got contacts at FluidHosting that are available at this time of day, perhaps you'll have more luck contacting them than I'm having at present (as an aside, I verified the status via several routes, just to ensure the problem wasn't at this end).
Attempts to phone them via the number listed in their WhoIs (860-656-6191) results in a message telling me the number is not in service. Oh dear.

Everything seems to be back up and running folks. A comment further down (thanks Mark_H! :o) ) suggests the problem was their entire DC going down. Again however, no idea this point as to what caused it to do so. Hopefully FluidHosting themselves will post information on what happened, to their site.

I've just checked the FluidHosting forums and found this (posted by "FH-John"), which explains what happened;
The thread is at the URL below, though you've got to be registered on their forums to see it (not entirely sure why). There's nothing on their homepage about this issue.
