Please note that content servers serve bits. Not bots.

Hm, "masters" don't have the bits, so I probably used the word "master" too many times in that email. The first paragraph was about how we manage our game servers. We do this using the exact same tools you could use to manage yours, our game servers do not have any special channel to the content or to the GMS. They are able to grab it at the same time your servers are. "Master" in that context meant the server in the datacenter that is responsible for calling hlds_update and hlding the "master" copy of all the bits we rsync to the real game servers. The "Game master server" is a Steam server (actually a few of them) that maintains the list of servers and services listing requests. Your game servers' heartbeats (previously sent directly via UDP, now for TF2 and in the future for all games through the regular Steam channel, but the same principle applies) talks to them. Sometimes the GMS is also called the "master server" --- I think that's QuakeWorld heritage. It really doesn't have any special status within Steam. The content servers are the ones that have the bots and from whence the super-lengthy download happens. We flip the "mast switch" to make new depots active after the latest versions of the depots have propagated to all of our content servers. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kyle Sanderson Sent: Friday, December 16, 2011 1:29 PM To: Half-Life dedicated Linux server mailing list Subject: Re: [hlds_linux] (ATTN: Valve) steam.inf missing and other "incomplete update" problems Sorry, the 'master switch' is flipped when all masters have the 'bits'? or after all the slaves have cloned?
