Frequently Asked Questions
What is a CDN and why do I need one?
A CDN (Content Delivery Network) caches your website on servers worldwide, so users load content from a nearby server. Benefits: 40-60% faster page loads, reduced origin server load, DDoS protection, and better SEO rankings.
Is Cloudflare really free for unlimited bandwidth?
Cloudflare's free plan includes unlimited bandwidth with basic features. The Pro plan ($20/mo) adds WAF, image optimization, and analytics — still with unlimited bandwidth. This makes Cloudflare unbeatable for high-traffic sites.
How do I estimate my bandwidth needs?
Multiply monthly pageviews × average page size. For a 2.5MB page with 1M views: 2.5GB × 1M = 2.5TB/month. Add video streaming, API calls, and downloads. Most sites use 100GB-10TB/month.
Which CDN is cheapest for high bandwidth?
For unlimited: Cloudflare (flat $20/mo for Pro). For usage-based: Bunny CDN ($0.01/GB) beats CloudFront ($0.085/GB) and Fastly ($0.08/GB). At 10TB/month, Bunny costs ~$100 vs CloudFront's ~$850.
What are CDN egress fees?
Egress fees are charges for data transferred FROM the CDN to users. AWS CloudFront charges $0.085/GB for the first 10TB. These can be significant — a 50TB/month site pays ~$4,250 on CloudFront vs $0 on Cloudflare Pro.
