It has come to our attention that CoD4 servers running on the default port may do very poorly in the server browser in comparison to other servers running on non-default ports. This does not show through the commonly-used 3rd-party audit tool at
http://www.anarchic-x.com/cod4master/audit.php but we have noticed it anecdotally after changing a couple of servers to different ports. As a result, we are considering a change to port 28930 for all our public CoD4 servers.
If a port change is something that you would NOT like done for your server, please let us know right away. Our current plan is to change over any servers that are completely empty tonight (Thursday night) to the new port on Friday morning, as a test. If the test goes well, we will send out another email next week to invite our other renters to change their ports as well.
As always, please let us know if you have any questions or comments about this or anything else. Please also let us know if you would like to test a different server port before our planned test tommorrow morning.
