Happy Eyeballs
Resolution Delay Test

We set up a DNS nameserver that introduces a delay based on parameters specified in the requested domain name. Our test sends a configured number of delay configurations for each DNS record type, allowing us to test how browsers deploy the Happy Eyeballs Resolution Delay.

We randomize domain names to prevent caching effects on both the browser and resolver.
