Late last year, I was forced to find a new host for movementarian.org, as my previous hosting provider (Blue Room Hosting, who were really great) were shutting down. I went with VPS247, as they were local to Manchester and seemed reasonable.
Unfortunately my experience has been terrible. They've failed to keep the machines on the net, regularly causing ssh sessions to die. The dmesg is full of warnings about the block drivers failing to write for more than two minutes: evidently the SAN setup they have is totally unreliable.
My VM went down for a significant amount of time and support were very slow to respond. During the total outage, there were no status updates, and no response on the support tickets or the forums. The penultimate straw was when my filesystem was massively corrupted. Even though my VM is hardly critical, I can't be doing with unreliability like this, especially when they're not reachable when problems occur.
My final straw, though, was when I discovered they'd deleted all the negative comments from the Client Comments section of their forum. That's really, really, not on.
I'm now with linode and happy (so far).
