Due to the low server population and lack of incoming funds associated with that, it was decided to move the inizicraft server to a less expensive machine. The new machine can still easily handle running the server, so there will be no performance impact or reduction in server render. The only negative is that the hi-res dynmap renders take up more space than is realistic for us to devote to them on the new system. (They were well over 20G just from what had been rendered up to this point.)
So while the Dynmap is a cool feature and we understand that it is greatly wanted, our first priority is to make sure that the server continues running and growing.
We are looking into ways to reduce the file space that dynmap takes up with the hi-res maps and we hope to re-add it as technical work-arounds or funds allow.
