Worst Hosting Experience Ever.
I used to use VPS.net. Everything was perfectly fine for the first month, and then when I removed that ispmanager crap and redeployed the vps using command line administration only (which I still do to this day, no control panel software) and for the first 3 months, it's been down like clockwork every 20 days. Always excuses from VPS.net "upgrade your nodes", which is translated as "give us more money" - when I upgraded my nodes, it continued happening, and it's nothing to do with the VPS, It's the actual service they provide, 'SAN's going down all the time, hard drive failure, that line on their homepage about "Self Healing" is utter bullshit.
Their support is not english, it's some garbled mess, they need to hire english speaking support staff, and seriously work on their uptime, it's a revolutionary concept, but they do not put it into practise so well.
