HE RD Test

A test run with 10 repetitions usually takes less than five minutes (10 x 5s sleep + measurements). Depending on your browser and device this might vary significantly.

One repetition uses about 15 kB of data. Therefore a test run with 10 repetitions uses about 150 kB.

Currently we collect the measured results together with userAgent, and vendor information. We do not collect or store your IP addresses as part of this measurement. If you want to help us to interpret the results you can describe the network environment as part of the device and user information input field. Measurement results are not transmitted automatically at the end of it. If you want to enable this feature, check the "Auto Transmit Results" box. If it's not checked you can transmit your results after the measurement ended.

Measurement Information

We setup a name server which applies a delay according to parameters provided in the requested domain name. Our test is configured to send a configured number of delay configurations for each record type. This enables us to test how browsers deploy Happy Eyeballs Resolution Delay.

We randomize domains in order to prevent caching effects on the browsers and resolver side.
