> I'd imagine 1.1.1.1 has a very negative consequences for Netflix local caches, for example.

Is it possible for Netflix to use anycast?

For their appliances they can advertise to an ISP's routers via (i/e)BGP or OSPF / IS-IS to keep traffic internal, but have a fallback of having a presence in various IXPs.

Isn't this how Cloudflare works, anycast?

Yes Netflix is anycasted at the edge. Has been for years.

Just because a given CDN uses anycast doesn't mean that they don't also use ECS as well. In fact, Cloudflare CEO's own wording seems to suggest that all of these mentioned providers still need ECS even though they do run anycast.

Basically, it would seem that Cloudflare is trying to close the performance gap by artificially limiting the performance potential of alternative CDN providers to match their own levels.
