My earlier 3fa58303d0dd206609362d68736f1039801ffd8d tried to implement the net/http.Tranhsport.DialTLSContext hook, but I didn't return a *tls.Conn, so we ended up sending a plaintext HTTP request to an HTTPS port. The response ended up being Go telling as such, not the /derp/latency-check handler's response (which is currently still a 404). But we didn't even get the 404. This happened to work well enough because Go's built-in error response was still a valid HTTP response that we can measure for timing purposes, but it's not a great answer. Notably, it means we wouldn't be able to get a future handler to run server-side and count those latency requests.
