DNS Records and Deno
so I am confused
I'm building an application that uses Steam's web API and am looking at why the response times are taking so long
and with the perf headers I have in my application I can see it takes a while to make the requests (260-300 ms)
so I investigated where Steam's API servers are located and found that there is one in Los Angeles
so I spun up an EC2 instance there and pinged the domain name
I used some online tools to find out that it's resolving the domain name to an IP that's located in Minnesota
so I found the one for Los Angeles and the latency was ~0.5-5 ms
which sounds correct, but using the
so I tried editing
but based on the latency of the request it's still resolving to the Minnesota IP
so I tried changing the IP to something other than a Steam API server to make sure that the manual DNS record was working
and it is working, but it's also not working?

/etc/hosts and adding in the host myself to make it resolve to that IP addressbut based on the latency of the request it's still resolving to the Minnesota IP

doing
ping on api.steampowered.com with the manually set DNS record works as expected, resulting in very low latencybut doing
fetch in Deno seems to resolve to a different IP address than what ping resolves toI can't just replace
api.steampowered.com with the IP (104.90.122.79) either because the server responds with a 400 Bad Request "Invalid URL" if I replace the domain name with an IPI've also made sure to restart the
systemd-resolved service after changing /etc/hosts
