I read on their forums a while ago (like a year ago) they was having problems getting a tech specialised in it or something like that. I haven't used HG for the best part of a year, when I moved the site to another host.
I'm looking for a VPS at the moment to host a side project, but I don't want the hassle of unmanaged and I don't wanna pay for managed, HG looked ideal as I only left them because their throttles/rate restriction resulted in some sites being painfully slow.
Edit: I currently have
http://www.dreamhost.com/hosting-vps.html, but their control panel makes me nautious.
