What Is True Web Speed?
True web speed measures download throughput to the CDN networks that deliver the real web — Google, Cloudflare, Netflix, Amazon, and more — not just one speed-test server.
Most speed tests measure a single nearby server. That number can look impressive but miss how your connection performs when loading real sites, streams, and app updates from content delivery networks (CDNs).
SpeedIP's true web speed score is the average of your five fastest qualifying CDN transfers — the same class of networks that serve everyday web traffic. You also see a per-provider breakdown so you can spot weak routes.
Upload is still measured to our edge server (browsers cannot POST test payloads to third-party CDNs). Download results appear first; upload finishes in the background.

Frequently Asked Questions
Why median instead of the fastest CDN?▾
CDN probes with very high time-to-first-byte usually mean a poor route to that network, not your overall capacity. SpeedIP averages your five fastest qualifying transfers (128 KB+, TTFB ≤500 ms) for the headline score.
Is true web speed more accurate than my ISP's test?▾
It answers a different question: how fast you reach real content networks, not just your ISP's hosted server. Both are useful — compare trends over time.
