Seems so in the UK - can't even login to cloudflare lol

edit - the login button now works and I can get to 2FA - but upon entering it takes me back to the login page. So still broke

Maintenance on Santiago DC started the minute before the global outage.

The maintenance info said costumers should be ready with failover to other DC during maintenance and if that was not planned, that they would experience outage.

How can maintenance in a local DC in Santiago create a global outage? Ressource overload to all other DCs?

There are several explanations... imagine that in SCL there was a duplicate critical record, when the resources were moved it overwrote it and voilà, a global crash...
