I quite like the way Google has drawn the map here-since no cables reach from India to Europe, they've split the map there making the paths easier to trace between Asia and NA. https://2.bp.blogspot.com/-QvF57n-55Cs/WZypui8H8zI/AAAAAAAAE...

Compare with the difficulties of https://cloud.google.com/images/locations/edgepoint.png

Elegant and subtle work. Just like the networking.

Nice find.

What is the ping time from India to Iran? That is a long trip for a packet.

I was going to ask the same thing, what's up with that. Why is there no continuous connextion?

There are connections, just not ones where Google own a stake. Here's a map of the submarine cables as of last year: https://cdn.arstechnica.net/wp-content/uploads/sites/3/2016/...

Back when I was in Google Netops we had a healthy (unofficial) fear of having the backbone connect all the way around the world in a circle, especially with high-enough bandwidth links that both directions would start to look attractive to traffic management.

Explain?

~260ms.

The route was Chennai-Amsterdam-Jordan-Iran

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.

You want to see some weirdly long ping times... try pinging Israel to Turky. Compare that to say, Israel to Netherlands.

Clever -- bummer if you are hosting in India and have Customers in the Arab world or vis-versa i guess.

Interesting observation.

You know when I saw that map it made me wonder which nation (or nations) those two large point of presences represent in the Gulf. It's Iran, isn't it?
