Geographic Routing: Route Users to Nearest Server

What is Geographic Routing?

Routes each user to the origin closest to their location.

Why Use It?

• Latency: Tokyo→US = 150ms. Tokyo→Tokyo = 5ms.
• GDPR: EU data stays in EU servers.
• Regional content: Serve localized content by location.

How It Works

1. City match

2. Country match

3. Continent match

4. Fallback (round-robin)

Limitations

• VPNs mask real location
• Corporate NAT may show wrong location
