AWS Status page doesn't show anything yet: https://health.aws.amazon.com/health/status

All our HTTPS (ACM) sites are returning:

> 421 ERROR

> The request could not be satisfied.

> The distribution does not match the certificate for which the HTTPS connection was established with. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner.

Lots of users seem to be impacted for a short time period: https://isdown.app/integrations/aws/amazon-cloudfront

My employer’s sites are hosted via CloudFront and seem to be fine. The underlying buckets are in Dublin, in case that makes any difference.
