OCSP or Online Certificate Status Protocol is a method used by X509 certificates to validate expiry or cancellation - think of it as the modern version of a certificate revocation list. A browser would contact the ocsp provider to verify if the certificate issued remains valid using its uid. Now its possible that Apple built a mechanism that performs this action for signed applications and this platform (ocsp) is suffering an outage. As a result, there's no response or an invalid one that's being returned. This may result in a requery and therefore people are seeing things hang or fail.
There are 2 potential issues at play here - 1) there is an invalid response due to failure or 2) apple is under attack at ocsp.apple.com
Since certificates are in play in all of Apples application services, there's a possibility something significant has failed (given the new release of Big Sur) and this is now hitting other services (like apple pay etc)...
Just a hypothesis...
