Longer notice for mTLS client certificate replacement

Change effective on 31 May 2023

Heroku now creates new mTLS client certificates for Private and Shield Heroku Postgres databases 75 days before the current certificate’s expiration date. You get an email with details of the pending expiration when we create the replacement certificate. Previously, we created certificates and sent notices 30 days before the expiration date. Certificates are valid for 13 months after creation, which remains unchanged.

See our mTLS documentation for complete details about the process.
