Decreasing Certificate Lifetimes to 45 Days (letsencrypt.org)

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

While I agree for my personal use, it's not so easy in an enterprise environment. I'm currently working to get services migrated OFF my servers that utilize public certificates to avoid the headache of manual intervention every 45 days.

While this is possible for servers and services I manage, it's not so easy for other software stacks we have in our environment. Thankfully I don't manage them, but I'm sure I'll be pulled into them at some point or another to help figure out the best path forward.

The easy path is obviously a load balanced front-end to load the certificate, but many of these services are specialized and have very elaborate ways to bind certificates to services outside of IIS or Apache, which would need to trust the newly issued load balancer CA certificate every 47 days.

Yeah, this has become an issue for us at work as well.

Currently we are doing a POC for an in-house developed solution where a azure function app handles the renewal of certificates for any domain we have, both wildcard and named, and place the certificates in a key vault where services that need them can get access.

Looks to be working, so the main issue now is finding a non-US certificate provider that supports acme. EU has some but even more local there aren't many options.
