This Sunday is the Superbowl, but we'll still be working to make Halo 2 better. On Sunday evening at around 10pm, the Halo 2 Stats display on bungie.net will be offline for approximately 24 hours. This only affects the web site display, not the collection of your game data or your Xbox Live play.
See, the problem is you guys play lots of Halo 2. So, our stats database needs to have some upgrades done to it to make sure it can handle the load. Bear in mind that your stats will still be collected as you play, they just won't be processed for viewing on the web site until the maintenance period is completed. We apologize for the downtime, hopefully we'll complete the maintenance faster than 24 hours.
