Is the calendar function down at the moment?

[Bill Johnson]

Everyone on the team gets the following error when attempting to navigate to to the calendar.  It was all fine yesterday and we did not make any changes I know of?

{"status":500,"error":"Internal Server Error","message":"403 null","timeStamp":"Wed Oct 02 23:06:31 UTC 2019"}

if you were previously logged in, it works, so must have something to do with credentials.  If you log in now or use incognito, the failure occurs.
