Why do you believe the inter-satellite links are not working?

[Due to the part of the spectrum I am on, I do not have believes or opinions.]

The laser based inter-links still not working has been subject on various conferences like AngaCOM etc.

But in my case: I have simply tried it *). And every Starlink user can do it, too: Use traceroute. And if you think "they might be hiding the hop-to-hops between Sats!", you can dig deeper using MTR behind the modem or simply rooting the modem itself.

Last time I have connected to a v3 Sat however was ~6 months ago. Maybe an active user reading this can try today?

You're equating occasional dropouts (which can happen for all kinds of reasons even in bent-pipe topologies) with the absence of inter-satellite links. That makes no sense.

The empirical way to test for the existence of ISLs would be to go to the middle of an ocean, safely out of reach of any ground station, and see what happens. If you get a connection, that can only be due to ISLs.

It seems like your actual complaints are with network/routing stability, and you're drawing invalid conclusions from there.

Do you have a link to a blog or writeup regarding the inter-links not working? Hard to find it without getting lost in "Troubleshoot your starlink device" SEO hell.

Here is an example thread of someone having done the measurements of v3 vs mini:

Have a look at the downtimes of the system.

A simple way to verify that their inter-sat links are not working and/or are not used is to simply sit and wait: If you are switched from one Sat to the next, you get new "session" and previous NAT state is lost. If this would be a meshed backbone, that would not happen.

This is ridiculous.

How's service delivered to the South Pole?

Iqaluit?

As long as your traffic is terminated at the same POP, you won't get any session terminations.

And Starlink tells you when your public IP changes anyway
