Snap was the external name for the internal project known as User Space Packet Service (abbreviated USPS) so naturally they renamed it prior to publication. I deployed an app using Pony Express in 2023 and it was available in the majority of cells worldwide. Pony Express supported more than just RPC though. The alternate RPC approach that you spoke of was called Void. It had been experimental for a long time and indeed it wasn't well known even inside Google.

If you and I still worked at Google I'd just give you an automon dashboard link showing latency an order of magnitude better than that to prove myself…

Maybe difference of a couple years. Maybe I was checking somewhere with older equipment, or some important config difference in our tests. And obviously my memory's a bit fuzzy by now but I know I didn't like the result I got.
