It's blocked for those who use Cisco Umbrella as sort of "moderated" DNS which blocks malicious sites already on the DNS layer. This is likely a paid service where threat intelligence, like Cisco Talos and other contributors filter or mask out flagged malicious domains from DNS requests of their clients.
