Pair.com is a terrible webhost. I run nothing but a vBulletin CMS and forum, and though it's a popular site, we don't go over either our disk space or bandwidth. They have disabled my website twice because we were "too busy" -- despite not going over the allowance that I purchased. They have also twice done something to their servers which corrupted my vBulletin, and on both occasions I had to hire a vBulletin developer to fix the problems, to hundreds of dollars each time.

I would advise anyone who is looking for webhosting to NOT use Pair.com unless you actually want your site to come across as unprofessional with very upset users.
