My halo reach account was reset

My halo reach account was reset. I would like to know why and can I recover my progress.

There appears to be some issues with Reach and other Legacy games at the moment including matchmaking services and the ability to pull information / stats from your profile. 343 are aware and are currently investigating. As we have multiple topics open for this I’m re-directing to a central topic that can be used to keep track of things:

Please also not that there will be maintenance performed on legacy servers starting tomorrow. You can keep up to date with that in this thread: https://www.halowaypoint.com/en-us/forums/36cecc379ca14abd918029d359551927/topics/reach-halo-3-odst-maintenance-5-29—5-30/408b60be-3604-4769-bd4e-bccccba64e38/posts
