Resolved Service Degradation

At 2:53pm PT on September 23rd, Okta's Engineering Team became aware of an O365 federation issue on all cells affecting customers federating new domains. During this time, customers federating new domains may experience a '400 Bad Request' error. Okta is documenting a workaround and developing a hotfix release to mitigate the issue. We’ll provide an update in 30 minutes, or sooner if additional information becomes available.
