Shared cache servers on an island's IXP

Thu Jan 18 14:20:11 UTC 2024

Many CDNs have hardware options for self hosted caches. I think there would
likely be concerns about <20G of connectivity to those caches though. With
an incorrect setup, you could end up maxing out those links just with cache
fill traffic itself.
