333networks monitors UT(demo) servers and provides you with server information and UT(demo) resources! Keep an eye on your UT server, read our tutorials and join our community! At 333networks, we try to keep improving wherever we can. We do this as a hobby, for recreation, out of curiousity, and to make new friends.

The end is nigh!

Yesterday (Sun 8 Nov) our primary server died. This is the first casualty in over 10 years. Please applaud the mighty service that k8v-x-333networks, or better known as phobos, has provided! We are now running on a backup server, but inevitably that brings us to the following.

So far we spent our own money on the servers and masterservers, because we don't want intrusive and ugly/inappropriate advertisements. We are getting more and more visitors/users, so we now started looking into ways to get some crowdfunding going. If you can think of a nice idea to cover our expenses, or if you want to donate, please let us know (irc/email).

Many communities now use the 333networks masterserver for their games. Admins, would you please ask on your forums whether your users would consider a small donation too?

In the meanwhile, we will look into ways how to receive your donations. With enough donations and fundraisers, we will be able to buy new hardware and provide faster masterserving. Thanks for your help!

333networks runs a MasterServer. This is essential for online gameplay. How does this work? Why is it so important that these MasterServers exist? And what happens if one of them goes down? Find out in this tutorial.



333networks also has a wikipedia now. We try to add new information regularly, but to complete our works, we need your help. Please contact us to get an account. You can find the wiki at wiki.333networks.com.

Admin Guide

Since the first Unreal Tournament servers were started, people wanted to play for pleasure. To make the game more enjoyable for all players, some player rules were written. But later on, some admins did not act as responsible and respectable as the players. Therefore, a second set of rules was written to remind admins how to behave and act honorable. These rules were combined into an admin guide.
