CDN Speed Test Guide
How to run a CDN speed test, read per-provider results, and interpret your true web speed median across Cloudflare, Google, Netflix, and other networks.
A CDN speed test downloads from multiple content delivery networks and reports throughput to each one. SpeedIP runs these probes in parallel so results appear in seconds.
Your headline download score is the median of qualifying CDN transfers — we call this true web speed. Expand the breakdown to see which providers are fastest or slowest on your route.
For the most stable result, use ethernet, close heavy downloads, and run the test twice if numbers vary widely.

Frequently Asked Questions
Why do CDN results differ from each other?▾
Each provider uses different edge locations, peering, and caching. Your ISP may reach one CDN's nearest node much faster than another.
What if a CDN probe fails?▾
Failed or cached responses are excluded. The median uses successful transfers above a minimum size so tiny or blocked responses do not skew the score.
