Let's Encrypt has become aware that we did not update our CP/CPS to include an explicit attestation that we comply with the latest version of the Chrome Root Program Policy and the CCADB Policy by 2026-06-15, the effective date of a new requirement to do so in Section 1.1.3 of v1.8 of the Chrome Root Program Policy. We were aware of the upcoming requirement and had tracked it in our public CP/CPS repository, but failed to make the necessary updates by the policy effective date.
We have filed a preliminary incident report at 2062418 - Let's Encrypt: CPS missing root program attestation; please follow along there for updates.
