My server that was known as dvcstable01.dvcnode.org is still running and is also known as LFM.knotwork.com, and still runs all the many and various coins it has been running all along.
Existing nodes should work as they will have it in their peers lists, some coins let you add peers while they are running others need them on the command-line when you start them or in their config file if you use the config files.
