He's the CEO, not the CTO. I don't recall Bezos ever giving a deep-dive talk about the metrics of AWS's networking stack. He left that to his tech folks.

I have absolutely no love for Ellison as you can see in my post history, but it's a bit silly to expect detailed tech specs from the CEO of a company on an earnings call with a bunch of investors that would have no idea what he was talking about if he did.

*I did in fact forget he changed his title when he gave co-CEO to Safra Catz and Hurd to rescue Hurd and not lose Catz in what was another of a long list of ethically questionable moves. It doesn't change the fact that he's completely removed from the technical details of their products and has been for 20+ years.
