since i started this i want to add some facts:
So far IMC hosted their server on AWS. Since many of you might have never worked with it, let me explain a bit. AWS is a server virtualization from Amazon. This means you don’t rent a physically server, it is created virtually on a server farm. It acts like a real server, you have full access, but it is just virtual. The benefits here are that you can launch a server in a matter of seconds and you can also scale its computing power, ram etc. in such a short time frame.
So, why is this important? Quite simple. IMC is talking about launching additional worlds when needed. Which is the equivalent to launching a new virtual server. Now comes the interesting part: AWS has many different locations for the server farms, some also in EU. When you launch a new server you just select the region from a dropdown menu and BAM you got a server in EU, NA or where ever you want.
So this means that for IMC to launch 4 worlds in NA or only 3 in NA and 1 in EU is just one click of extra work. All of them need to be hooked up to the login server(i assume IMC has one server handling the logins of users) and for AWS it does not matter to which server farm they belong. They can all be connected. This might involve a few extra minutes of work because you need to create a new security group for the EU server but i have done this many times and can assure you this is about 1 h of work at most, if you are new to it.
So saying they cannot provide an EU server in such short time is not true IF they are still using AWS for the final release and IF they don’t have some other limiting factor like all worlds being on the same server and them launching a new world is just raising the hardware power of the virtual server (which i doubt because this would raise so many other problems in the future).
In short: AWS makes it super easy to add another EU based server, if they use common architecture.
