Major outage. All regions. Unable to open documents.
Incident Report for Onshape

An internal coordination service (ZooKeeper) encountered an error and failed. This service quickly recovered. Unfortunately this disconnected all of the application services that were connected to ZooKeeper causing all modeling sessions to be kicked out.

We are working with our engineering teams to prevent this problem from recurring and making some changes so that a similar failure will have less of an impact on the service.
