The change is driven by CA/Browser Forum Baseline Requirement 3.2.2.9, which from 2026-12-15 requires CAs to use at least five remote Network Perspectives for Multi-Perspective Issuance Corroboration, spanning at least two distinct Regional Internet Registry service regions, or refuse to issue. The stated goal is better visibility and protection against BGP attacks during validation. Why: If your certificate issuance relies on HTTP-01 challenges behind geo/IP allowlists, split-horizon DNS, or region-locked CDN/WAF rules, validation requests will now arrive from more places and a blocked perspective can fail issuance. Before the 2026-12-15 requirement bites, test that your challenge path is reachable from multiple regions rather than only your usual datacenter, and check any firewall rule that whitelists Let's Encrypt validation IPs. tls certificates infrastructure web-security acme

Let's Encrypt is adding two additional remote perspectives for domain validation
