We got this email from GS:
[q]Hi Dynamic Site Users,
We have been working to improve our dynamic server performance over the last several months. As many of you may be aware, we now have a clustered and load-balanced server farm supporting your dynamic sites - we no longer are setup with standalone servers.
Yesterday we made a change in the way we handle dynamic paths. DynamicX(2 through 6).gamespy.com now permanently redirect to dynamic.gamespy.com. This may have affected the functionality of your PHP scripts, if you have utilized hardcoded paths.
We have run a scan and replace for dynamicX.gamespy.com to dynamic.gamespy.com to correct such problems. We also would like you to manually check your code and utilize dynamic.gamespy.com in future coding.[/q]
