When I connect to the Surrey server on undernet it takes me to Lelystad.NL.EU.UnderNet.Org.
I'm looking at the servers for Undernet but it don't seem to list the Surrey one
here. There are however 2 London servers listed.
[*]London.UK.Eu.UnderNet.org
[*]London.UK.Eu.UnderNet.org
You might want to try the networks help channel (#help, #services, or equivalent).
