OK. Where do I start?
I've been on a VPS for the last two weeks (many thanks for the coupon Emmanuel) and I must say that I am very impressed.
During the last two weeks I've only been through two server reboots and the one was due to a SSHD spam attack that caused the server to reboot. Thanks to support's tutorial on how to use iptables (and banning half of China and Cuba) everything is running well.
Speed wise the server is very impressive. Very quick and sharp responses. The major thing for me was the server downtime which I have not had in the last two weeks.
Support migrated all my accounts from Pass11 (except modsdxd - must chase up support

) smoothly and quickly.
Regrets? None. I am beginning to have more confidence now with reselling services based on my VPS as opposed to being on Pass11.
