    Cloudflare adds DNSSEC bypass warnings for .AL outage

    A failed DNSSEC key rollover in Albania’s .AL TLD caused validation errors across the zone, making many domains unreachable for users on validating resolvers such as Cloudflare 1.1.1.1. Cloudflare applied a Negative Trust Anchor to restore resolution and, for the first time, returned an Extended DNS Error code to indicate that responses were served without DNSSEC validation.
