Inspired by Mackin's SAD tale. Sorry rather boring rant...
We've just this weekend decided to go from an early dedicated server at Pair to a current version. The process has gone to shit, no emails work for any domains (all static sites are fine, and even a couple of the smaller WP sites are ok). A large WP site that we are developing (backed up) and a drupal site I use as a playground have all but disappeared. I'll start getting it in the neck and arse once the US offices open up and have no emails, etc.
Been with pair for years and never had any serious problems. Compared to hosting issues experienced in the UK, they've been Saints. Hoping for a quick resolution...
All resolved.
