264w ago - Rod Fergesson, the Senior Producer from Gears of War 2 has outlined on the official forums (linked above) the problems with their online matchmaking service and acknowledges that and patch will be released in the near future to counter the issues.
To quote: We're aware that some folks are experiencing longer-than-ideal wait times while using the skill-based Public matchmaking in Gears 2 multiplayer.
We're working on some solutions but it's a complicated issue as there isn't any one problem; it's a combination of factors. Clearly, scale is one of them as we've had millions of successful matches played online so far, however a small percentage of players are having issues, which is unacceptable.
We're working closely with Microsoft to address the matchmaking issues, I promise you that it is our #1 priority, and we hope to have an update soon.
In the meantime, I would like to suggest some workarounds:
If you're experiencing long delays (longer than 2 minutes) or you're seeing your matchmaking search restarting over and over again, please try a different playlist as that indicates a possible population issue with the currently selected one.
The problem seems to be heightened for parties of 1 and parties of 4 so please try to invite at least one friend...
