Internet Speed Test

Measure real download, upload, ping, and jitter against Cloudflare's global anycast edge — directly in your browser.

The full speed test runs in our gauge view for accurate parallel-stream measurement.

DNS lookup

Slow loads are often DNS, not bandwidth.

Ping & latency

Test sustained latency and jitter.

Packet loss

Find the dropped packets ruining streams.

How it works

  1. 1
    Parallel download streams

    Four concurrent HTTP/2 streams saturate your link for an accurate Mbps reading.

  2. 2
    Symmetric upload test

    We POST equal-size payloads to measure upstream throughput.

  3. 3
    Latency + jitter

    Eight tiny pings, trimmed mean for ping, mean absolute deviation for jitter.

Real use cases

  • — Verify your ISP is delivering the speed you pay for.
  • — Compare WiFi vs ethernet on the same machine.
  • — Diagnose Zoom, Teams, or gaming lag.
  • — Test before and after a router or firmware change.
