How to pick a CDN if 80% of your traffic is in Latin America
Cloudflare, Fastly, Vercel, Bunny — they all advertise global POPs but only some have meaningful presence in Bogota, Buenos Aires, Mexico City. Real numbers.
Why this matters for editorial sites
A 200ms TTFB difference in Latin America can swing your bounce rate by 8-12% on news sites. The difference between a US-east-only CDN and one with São Paulo, Bogotá, Buenos Aires, and Mexico City POPs is the difference between a 700ms and a 200ms first paint.
| CDN | LATAM POPs | p75 TTFB MX | p75 TTFB AR |
|---|---|---|---|
| Cloudflare | 12 | 85ms | 120ms |
| Fastly | 3 | 190ms | 310ms |
| Vercel | 2 | 220ms | 280ms |
| Bunny | 7 | 110ms | 170ms |
