Let's Encrypt is adding two new remote perspectives for domain validation. This change is motivated by the fact that increased perspectives provide more domain validation security and is required by the Baseline Requirements which is quoted below. Increasing the number and coverage of our domain validation perspectives improves visibility and protection against BGP attacks.

BR 3.2.2.9 Multi Perspective Issuance Corroboration Effective 2026-12-15, the CA MUST implement Multi-Perspective Issuance Corroboration using at least five (5) remote Network Perspectives. The CA MUST ensure that the requirements defined in Quorum Requirements Table are satisfied, and the remote Network Perspectives that corroborate the Primary Network Perspective fall within the service regions of at least two (2) distinct Regional Internet Registries.
