1. Why Game Servers Are Unique: The Challenge of Stateful UDP Traffic

Unlike web traffic (HTTP/HTTPS) which operates over TCP with predictable handshakes, multiplayer games (Minecraft, Rust, Palworld, CS2) rely on connectionless UDP packets for ultra-low latency.

Because UDP headers lack sequence numbers and connection state, malicious actors can easily forge source IP addresses, launching massive UDP reflection and amplification attacks (NTP, DNS, CLDAP) directly targeting game server ports.

2. The Cloudflare Spectrum 300+ Tbps Anycast Shield Architecture

Enzonic integrates enterprise Cloudflare Spectrum Anycast scrubbing centers across 330+ global cities in over 120 countries. Inbound traffic is announced simultaneously from all edge data centers.

When a 1.5 Tbps volumetric DDoS attack is launched, the traffic is automatically dispersed across hundreds of global scrubbing nodes and cleaned in-line with sub-millisecond overhead before reaching your game container.
