"Issues with Magic Transit and BYOIP" apparently, looks to be identified now.

Brutal given the reliability stuff they were boasting on R2 just today.

Or, wonder if related to an announcement and push tonight for it. Better unpublish that Birthday Week post! In all seriousness wish engineers well and best of luck resolving.

Seems to coincide with Bandwidth's outage: https://status.bandwidth.com/incidents/d8vft1kpxdmk

Wonder if has to do with Let's Encrypt's Root Certificate expiring. That's my guess; some supporting infrastructure didn't update.

Yes, looks like they're having a large outage
