By definition, however, RTT is "the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgement of that signal to be received."[2]. So if DNS TCP measurements starts measuring from the SYN packet, that', in fact, be two RTTs. Is this the case with Atlas?
The use of RTT on that page is wrong. The DNS measurement reports response time. Philip
