I imagine TheSockStealer was wondering about India to Iran ping time through Google's private network (the one in the diagram upthread), which doesn't appear have a connection from Chennai to Amsterdam.

The packets in the trace you posted were presumably routed by someone besides Google. Or did you run that traceroute from inside GCP?

Or I could be misunderstanding the diagram and maybe Google has some connections that aren't shown. I don't really get what the ">100" in "edge points of presence >100" means in the legend.
