Booking.com's Terms and Conditions page was updated on April 9, 2026, but what was detected appears to be a technical security challenge page rather than substantive terms content — specifically an AWS WAF (Web Application Firewall) bot-verification page with an updated security nonce/token. The visible change is the rotation of an internal security token value from '17755421549470' to '17757148383100', which is a routine infrastructure update. This does not represent any change to the actual consumer-facing terms of service content.
