It seems that when using the Fastest_address mode with a domain that has mutiple CNAMEs, AGH only tests all IPs of one CNAME, not all IPs of all CNAMEs, so the returned IP may not be the fastest one.

See this domain cf.shopee.vn as an example, keep in mind that the zshopee.v.baishan-cloud.net cname is the fastest address. AGH should always return the fastest one.

The fastest check algorithm seems to check the TCP connection time to port 80/443 rather than the ICMP response time?
Not sure what one is more accurate. :/

Sorry, the tests are not really accurate.
