The Valhalla map server was abandoned due to lack of development from the map creator and no interest from public. In its place two new servers have been launched with the two official maps running on them.
The gorgeous Center map and the the well known Island map. These servers are here to stay as they both run quite efficiently on one hardware. If there are some hiccups on the load and the popularity of the servers rises I will consider moving them to separate machines but as of now the server runs at 30% so they should both be OK – tested by several hours of gameplay by two players.
I am actively monitoring the server 24/7 and all request sent in chat will be responded to sooner or later.
