ok, paypal.com 302s to www.paypal.com # curl -I https://paypal.com HTTP/1.1 302 Moved Temporarily Content-Type: text/html Content-Length: 161 Connection: keep-alive Location: https://www.paypal.com/ Strict-Transport-Security: max-age=31536000; includeSubDomains So firefox must be checking the cert first before the redirect. But other browsers may be processing the 302 THEN checking and seeing the valid www.paypal.com -bill On 10/14/22 3:23 PM, Alex Cohn via Outages wrote:

I'm getting a "revoked" OCSP response for the cert currently used by paypal.com <http://paypal.com>, but a good response for www.paypal.com <http://www.paypal.com>. The naked domain is using OCSP stapling and is serving an older valid response, which is probably why it's still working even on browsers that are configured to check for certificate revocation.

The two certificates are https://crt.sh/?id=7746738574 (revoked, used by paypal.com <http://paypal.com>) and https://crt.sh/?id=7754586913 (valid, used by www.paypal.com <http://www.paypal.com>).
