BeastNode have moved all their servers to a different location. This means that every servers IP has changed. Which also means that you will not be able to connect to mc.dkcraft.net until a couple of hours.
I have made the necessary changes to link mc.dkcraft.net back to the new IP, but like I said, it will take a couple of hours.
For now, you can use the new IP to connect: 72.249.124.170:25565
This has been resolved, feel free to connect with mc.dkcraft.net once again.
Voting is also working once again.
EDIT: This seems to be affecting different locations at different times, so some of you may be able to connect with mc.dkcraft.net, and some of you may not.
Thank you for your patience.
