Apenwarr's code sends short HTTP queries of the format shown below to each of two hosts:
The Blip tool shows ~60-70ms for the gstatic host, and ~130 msec for the latter. Ping times are ~52 msec and 125msec, respectively. These times seem to track response times by my eye (no serious analysis) to load both on my primary (bloated) router and CeroWrt.
Still a cool hack.
HTTP Request & Response for typical blip "ping"
