Free certificate issuance with degraded performance

This incident has been resolved.

We identified that this is due to an issue currently experienced by the Let's Encrypt service. Existing certificates on custom domains will continue to function as normal - however new and cert renewals via our free certificate option may experience errors to the certificate issuance.
