I will have the server migrated to a different host today in the evening (afternoon for you US folk). This will take around 30 minutes, as the entire disk is copied over, during which the server will be down.
Reason for that are the lots of performance alerts the server has been logging over the past two weeks. The game client compensates for a lot of things, but knowing that the server sometimes hangs for 2-3 seconds straight - isn't exactly what I like.
Today it has been particularly bad, so this is really the time. ;P I reported the issues to them, and they will first move everything to a different machine, so I am giving them the chance to resolve the issue. What's causing it? Well, while developing I am using a shared machine (virtual server) instead of a dedicated server for cost reasons (and also because a virtual server is sufficient for what we need so far). Downside is that there are other servers running on the same machine, and my guess is that one of the neighbours on it is bogging it down. It's started in January, and since I didn't change anything (and also because the performance is fine at other times), I suppose that's when they "moved" in on it. XD
So, if this gets it resolved, great, otherwise it's time to move providers. ;P
