I run this site on an OpenVZ VPS from weloveservers.net. They've been very responsive in the past but I've had a couple of issues that I finally traced down to a OpenVZ configuration limit. I asked them to bump it up just a bit and they ran it up to almost unlimited or as close as you can get. A number of the other limits were similarly increased. I think my reliability problems might just go away. Cudos to weloveservers.
They didn't live up to expectations. I had to dump them.
