Summary:
On August 1st at approximately 1 PM PST, production experienced a limited partial outage that affected at least 2 customers. Users who navigated to the AdminUI with an expired authentication due to session timeout were presented with an error page. Normally, those users would be redirected to a login page. This affected CLI and Desktop SSO logins as well.
Impact:
Users that had already had an authentication which had expired would see an error screen when going to the AdminUI. Valid authentications or logged out users did not see the issue. Clearing the browser removed the issue
