If under caches you mean caches in the end-AS then the only work that has that ability is Akamai which has a very large number of pops located inside eyeball networks.

Cloud Flare does not. Cloud Front does not. Fastly does not. Google does not. Level3 does not. Even Limelight/Edgecast which used to have a decent footprint inside Verizon does not.

That in turn means that all of the content cached by those networks still relies on the eyeball networks having interconnect capacity.

I'm pretty sure I remember being shown a Google Cache box in an ISP data center a couple of years ago - and a netflix one as well - and I think an apple one - but not sure. I do remember there being a lot of fuss with iOs updates and they got persuaded to put them in a cache.

Maybe I dreamed it.

Netflix does but it is not that big size wise. It downloads current hot content. With COVID-19 a lot of long tail is now being consumed, not enough to push it onto the cache boxes but enough to strain the interconnects. When Altered Carbon 2 is released, it will be on the Netflix box because a good number of people at the edge would be requesting it. On the other hand some independent flick won't be on it because there are only a few devices requesting it at the same time.

Google used to have some search appliances, which they gave to ISPs. It is not the same thing.

Apple used to use Akamai for distribution of content because of racks that Akamai had in lots of edge networks. I do not know if they are still using it but I expect they do. Akamai has an enormous foot print.

I did an EU project where the tenant was that 90% of content consumed on a mobile network in a day was 1TB total! But yes, the tail is very long.
