Fast isn’t always stable.

See the latency spikes, jitter, and connection drops a quick speed test can miss. Follow your connection over 20 minutes, with measurement gaps clearly marked.

Exploratory preview: Germany reference and Cloudflare relay loop

This build measures probes to the Jitterglass reference server in Germany and a loop through Cloudflare's relay while the page stays open. The speed check and background use are not available yet. No probes are sent from this page.

Germany reference server

Independent 30 Hz probes in both directions.

Cloudflare relay path

A separate relay loop for comparison.

20-minute session

Brief speed check in the first minute, small probes after that.

Measurement coverage

Gaps in measurement are shown separately from connection problems.
