we encountered connection problems of all APs in all regions between Feb 18th, 20:00 UTC and Feb 20th, 01:00 UTC . The APs were still operational but weren't able to retrieve configuration updates or upload any traffic data. This was caused by an issue during certificate renewal. We have a mitigation in place and are working on a permanent fix.
The issue caused APs to be shown as offline. Also, deletion and registration was affected. Please refrain from any (re-)registration until we give notice that this issue is resolved permanently. We're sorry for any inconvenience.
