The transition to the new server went about as smooth as one could hope. After a few tricky hurdles, we are up and running on a new OS and hardware.
Some developments along the way:
Our Infinity Evolved Skyblock [MKS] server instance is updated to the Recommended version on the FTB Launcher. This is an unofficial instance, without a special spawn developed. For details on this server, registered users should visit the Resources tab.
I have also established an instance of the Block19 modpack, based on Minecraft 1.9.4. This modpack is available on the ATLauncher. Details for accessing the instance are available under the Resources tab.
EDIT: Block19 was fun, but we had to put it down. Hopefully it will resurface again with maturity.
I have not yet set up a 1.10 vanilla server, but that is coming in the [near] future. If anyone is interested in this, I can make it more of a priority.
