I have two VPS accounts with eUKhost and while I am very satisfied your post did caught my attention. Because you post in the same timeframe while I have issues with one of my VPS accounts that is hosted on the IP
213.175.214.74
I have submitted a ticket yesterday about it. The reason is that I can reach that server on and off since last Friday. Either the connection will time out, or the websites load very slow and often when they do load, they load up incomplete (missing images / css files etc.).
The weird thing, I face the same issue on eUKhost.com as well since last Friday and they are hosted on IP
213.175.192.12
Also when I manage to login at my WHM account all seems to be fine with low server loads. I somehow suspect connection (routing) issues between my geographic location to the IP range
213.175.x Atleast that is what I notice looking at the sites that gives me troubles to load. And your post seems like you face the same issue.
I hope it can be solved, I am awaiting a reply in my support ticket. Just posting here as well so support staff might see a relation between our issues.
(now lets copy my message in case I fail to submit it in once)
