Top definition
A general term used for excessive blocks/restrictions on internet access.

The term derives from port 443, the HTTPS or "secure" port. Often times, students at schools or employees under a restrictive firewall would bypass web filters by using port 443 instead of 80 (standard HTTP). Once this caught on, administrators across the world started blocking port 443 on their restricted networks, leading to "443 owned in the face."
