In the 6(!) years since we launched our Let's Encrypt SSL certificate provisioning service, we've left expired managed certificates in the database at https://my.opalstack.com/certificates/.
Over time this has left a lot of useless data in the system so beginning on Monday 16 June 2025 we'll begin deleting expired managed certificates and will delete them immediately after renewal going forward.
This only affects Let's Encrypt certificates that we generate and manage for you - if you manage your certificates manually they will not be deleted.
