Note: that was for a dedicated 10-gigabit link from specific location A to specific location B, plus a peering at one large IX, without any access to the rest of the internet.

Nonetheless it does give a ballpark for the cost of bandwidth being a lot lower than people think. A 10G internet connection would be cheaper to provide in some parts of that equation and more expensive in others - should end up in the same ballpark.

By "above" I meant ckdarby's number.

And honestly 10 cents per Mbps sounds kind of high for raw transit, I interpreted it as a price for actual utilization.

It was more than 5 years ago and was not a direct commitment. Another company was being used for their data centers, and this was a lease/rental agreement of equipment; Think colocation model, but where you're like 50-80% of being the main client of the data centers.

Add 10-25% profit for that company to get closer to true "raw transit" pricing from the carriers directly.

Also, can you show me any public pricing that is 100x cheaper than AWS? With same QOS! Or are you just throwing numbers around?

What specifically is the QOS for AWS?

But sure, if you want citations for $0.10 per Mbps in bulk for transit, that's easy to find/beat.

https://he.net/ "Get BGP+IPv6+IPv4 for $0.06/Mbps!"

https://www.fdcservers.net/ip-transit Europe, North America: 10Gbps $499/month

And telegeography just sells information, but they had a blog post that's now three years out of date reporting that "In Q2 2021, the lowest 10 GigE prices on offer were at the brink of $0.09 per Mbps per month. The lowest for 100 GigE were $0.06 per Mbps per month."

You need to factor in that your utilization won't be 100%, but if you're comparing 6 cents for a Mbps and and 5 cents for a gigabyte, then the exact point where AWS is 100x more expensive is when your line is 36% utilized.
