We had the exact same issue for our Australia hosted instance (no issues with our UK tenant). As with other comments this started working yesterday after mid-day UK time.

 

We also logged a ticket with Microsoft but have not had a response in the last 24 hours or so.

We reported the incident as a P1 also and they have been less than helpful (Mindtree on behalf of Microsoft). They suggested I speak to my Network Administrator (which is me 😂) in order to troubleshoot the issue at my end!
