Ask HN: StackExchange down for anyone on Firefox specifically?

It works on Chromium, but on Firefox on multiple machines with a profile with no plugins I get the following:

Secure Connection Failed

An error occurred during a connection to stackoverflow.com. A required TLS feature is missing. Error code: MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSING

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

Yes, broken OCSP stapling.

Note from the StackExchange Status twitter account (@stackstatus): A new TLS certificate is failing to send certificate status data that’s required when using Firefox. We’re working with our CDN provider to roll back the change.

Yup. I can confirm.
