I've been with Switchlink for just over a year now, I currently have the VPS-500 inc Plesk Panel from them (details: http://www.switchlink.co.uk/linux-virtual-servers
What I host
With them I host my website: www.netsky.org.uk
and also a 500slot Teamspeak 3 server (info: www.teamspeak.com
Their support over the past year has been really great for example: Martin, lastnight (which was a Sunday) at 11pm - 1am helped me reinstall my VPS, he had the whole process done in about 15minutes.
The up time for my VPS has been really good, before I reinstalled the up time was at 72days and that's only becuase I restarted my VPS one time.
I would highly recommend Switchlink, they do some great packages.
Great up time, fast support response time and the quality of the VPS's are really top notch.
