I have been a customer of this company OpenITC.co.uk for almost 1 year and 8 months and I would like to share my experience with them. First of all, to remove all doubt , below you have 2 images that prove that I have been a member with them for the time I specified and also the servers I have with them.
It all started when I was searching a small server with not so many resources in order to host a Team Speak server for the online gaming community that I administer. I searched for the "VPS Hosting Offers" section and I discovered several offers among which where the ones from XenVZ.co.uk aka OpenITC.co.uk. There was a wide range of servers at low prices. I had nothing to lose, so I chose them.
What I liked about the first order was that they had their own billing system, they do not use WHMCS software like 80% of the other companies out there. Activation was instant, there was no need to wait. Besides this, when I accessed the Control Panel I noticed they also had their own unique Control Panel for administering the server.
After this short story came the time to purchase other servers for other projects we had (ZNC Server, Shoutcast...) small things like that.
As for uptime, apart from "Scheduled Datacentre Migration" there was no downtime, and all of these breaks were announced ahead of time via email in order to inform the clients to take appropriate measures. I have nothing bad to say about technical support.
The uptime can also be proved to be accurate to my description by accessing the Team Speak server that I'm hosting with them. Below you have a recent screenshot that I made.
(of course I can give you a direct printrscreen through SSH of the uptime if you want to)
The support reaches a Superhero level, I mean they are very fast, this by using email. Of course I would've preferred if they used tickets, but email is ok too (as for phone calls, I have not used it because there was no need).
By and large I have nothing bad to say about this company, I am very pleased with their services and I plan on sticking with them.
I recommend everyone to give them a chance, try them out, see for yourself.
