A phased approach to reducing the validity of TLS server certificates over the next two or three years, ending at a 45-day certificate lifetime by early 2027.

Cert validity intervals directly affect the storage and bandwidth requirements for CT logs, which should be replicated.

Does anyone serve the CT Certificate Transparency logs for checking by browsers?
