This is explained (not fully) on http://deb.debian.org/ if you care to read it.

DNSSEC status of deb.debian.org
Hello, I was checking the Debian domain, and noticed that it is DNSSEC compliant. However, when I check "deb.debian.org", the DNS validation fails. After checking the status using Verisign (https://dnssec-debugger.verisignlabs.com/deb.debian.org), I understand Debian is using a CDN (Content Delivery Network). Is there a stable domain we can use that doesn't rely on a CDN, please ? Thanks, André Rodier. PS: Sorry to send an empty subject before.
