Okay, following back up now that we’ve got confirmation everything is stable again.
All servers should be back online at this point. Sorry for the hiccup. We’re looking into the root cause of these to see why they’ve happened this weekend to try to prevent them going forward. Thanks for all the reports and being patient while we got this resolved.
Note that some progress rollbacks are expected whenever this sort of thing happens as your character only saves periodically. If you are missing quest items (ex. horardric cube, etc), you should be able to go back to the original place that you received them to reclaim them. Any other items would need to be farmed back up manually, as there’s no way for us to verify or restore any progress in Diablo II: Resurrected.
If your character is stuck in game, it should resolve within about 15 minutes. Anything that takes longer than an 24 hours to un-stick should be reported here so we can look into it. We’re still checking these as they come in to figure out why some characters end up locked.
Either way, best of luck when you get back in.
Edited: Update 9:30 PM Pacific Time - there’s a different incident happening now. Please follow this thread for updates.
