I can answer your queries about Interhost, as I used to be a Windows
VPS Hosting customer, but I left because the support was sh*t.
Their hardware is all Dell & Cisco, I know that for a fact because of the details registered in the sys info of my
VPS Hosting which I had with them, they also have pictures of hardware on their
website hosting. They also don't have any 24x7 support, live support, forums or messenger support. As far as I'm aware, Interhost is only 1 guy, since when I phoned them it was only 1 same guy who answered. For
VPS Hosting, they had a separate subnet, which quickly got filled up, and started using IPs from the Centrehost (not very professional?). Centrehost is also 1 guy, and I think the guys Centrehost & Interhost are friends, since once when I phoned Interhost, I spoke to the guy who ran Centrehost. On several occasions I had to phone to get my support tickets answered, sometimes I never got them answered, or had to forward them for attention. As far as BackUps go, they never backed me up, never ever! Their knowledge level of Windows didn't appear to be much either. Everything was always answered by the same guy, everything (technical, billing & support) and all data centre problems were reported to customers by him, so as I suggested, I think it's only 1 guy. Even cancelling with them was a drag, it took me a couple of days, and I phoned, and they just said that it had to be done by email (very frustrating!!!). How they have so many customers is crazy!
eUKhost Windows
VPS Hosting are much better than the ones from Interhost, because they work! I remember building a webpage which contained flash, and I put it on my
VPS Hosting, and the flash file didn't play, and I had registered its mime type etc etc, and the page worked on my local dev server. I also had an instance of something else not working, but I've forgotten what it was now.
So to sum up:
eUKhost are 10000000000% better than Interhost, both support wise & technically. Anybody thinking of going to Interhost.... you must be crazy! And I just want to thank the eUKhost sys admins for the support they have provided me with in the last couple of weeks, and I'm sure their high standard will carry on.
