Yes same thing happening to us.  Was working this morning but randomly stopped about 15 minutes ago.

Glad it's not just me. On the line with Support about it now, will post what we find out.

 

Note: We're on N426, incase this is a node specific issue.

Spent ~30 minutes on the call while the rep looked into the problem. Had to bail due to a meeting. No progress made thus far.

Looks like it resolved. My team is able to get back in now.

Did we ever find the root cause?

I asked via my ticket, but I got a pretty general answer. Not a direct quote:

 

Engineering implemented some back-end changes which inadvertently irritated SAML. The changes were backed out, which resolved the problem.
