From Subnova comes word that Frigidman of Evihcra has set up a Marathon: Resurrection game server. M:R is a Marathon-themed mod for Unreal Tournament. Frigidman's post says:

We have setup a game server for M:R UT. It is in beta at the moment, and since none of the M:R team seem to want to test it out... I am forced to go to the public to have test it.

UT Game Server Name: online.evihcra.com

In the forum thread, Fm also notes that Evihcra hosts the 436 update and bonus packs for UT.
