As always, apologies for any interruptions this caused. We're still getting to the bottom of this. This incident was caused by another attempted update to our server code. We're going to hold off on performing this kind of update until we're 100% sure that we've got this fixed.
Edit: ~5:30 am PDT, there was a lingering issue causing DMs to notify the client for approximately 1/3rd of users. It also should be fixed now.

Identified
We've hit the power button furiously on a couple core services and things are coming back online. We're monitoring as things recover, but connectivity should continue to be restored.
