Kind of. Im pretty sure “public endpoint” is to disambiguate from virtual network functionality like VPC Endpoints and VPC Peering etc which are specific to you

Kind of. Im pretty sure “public endpoint” is to disambiguate from virtual network functionality like VPC Endpoints and VPC Peering etc which are specific to your account/VPC. To your other comment, not many companies own the “layer 0” physical infra long haul. But yes, this is almost absolutely going over “dark fiber” that AWS is leasing from someone like zayo or L3. Since 2016ish effectively all AWS regions and DX POPs use this model to interconnect. The LAX & NYC sites are almost definitely the same DCs & TCs used for “local zones.” So yes, a few hundred gb to tb of leased lines back to PDX and IAD. Search for “aws backbone” content. And for security Im not sure whats public these days, but fiber taps are a real and known threat. Source: ex AWS PE who spent some time in and adjacent to edge networking.
