This reminds my of 'chaos engineering' and the approach that Shopify took with 'Toxiproxy.' Toxyproxy is this elegant system that provides a REST API for spawn proxy servers. The proxy instances can have 'toxics' added to them that change the connections properties. E.g. you can add latency, packet drops, even experiment with slicing up packets. It allows for something like writing deterministic tests that test whether your software works under many different network conditions. I think its honestly a really smart design.

Very cool.
