The server will be up and running in just a few moments. you can access the server either by starting up HL2 - Deathmatch then click on the option for searching for a server.
The server is password protected and VAC secured. by clicking the symbols on the top of the server list you can sort out all the password protected games from those that are not then search for the Giveawayoftheday Half Life 2 - Deathmatch server.
Or alternatively go to the Steam giveaway page and click on any community member that's already in game and select from the drop down menu join game.
