Let's Encrypt will expand its multi-perspective domain validation from four to six remote vantage points, meaning each certificate validation makes seven requests. The change anticipates a CA/Browser Forum rule (BR 3.2.2.9, effective December 15, 2026) requiring validation from at least five perspectives across two registries before issuance.
