Please note that this is courtesy notice and no action is required from you if you do not pin intermediate certificates from Let's Encrypt (LE) and/or Google Trust Services (GTS) in your environment when connecting to Atlas dedicated clusters.
Let's Encrypt (LE) and Google Trust Services (GTS) have issued additional intermediate certificates to their services. Intermediate certificates act as a secure bridge between root CAs (e.g. LE/GTS) and end entities to streamline management and reduce risk. We want to emphasize that the changes mentioned below related to intermediate certificate authority are not made by MongoDB but by LE and GTS sometime in 2026 which are the Certificate Authority (CA) providers for TLS certificates for all MongoDB Atlas clusters.

We have identified the root cause and are working on backfilling those records with AWS support.
We have also disabled that ip range for new clusters so moving forward this issue will not be hit for new AWS clusters.
