Starting in May, Let's Encrypt will no longer use a cross-signed root
certificate, and the primary TLS certificate handling the `*.maxmind.com`
domains will be impacted by this change.

**Most customers will see no impact from this change.**

This change should only be of concern if the servers interacting with MaxMind
domains are running a very old or out of date operating system, or if you manage
your own local Certificate Authority store.
