Some backbone providers don’t appreciate the value of having on-net caches and/or do not want to consume the space/power to host caching. This is especially true with transit/backbone providers who build pops in cities using 1-2 racks (enough for core router, core switch, maybe some redundancy, and fiber patch panels). It’s a lot simpler to just peer with those providers on fiber you already have or can connect easily.
The downside to on-net caches is the space/power. If you are pushing significant traffic and have the space/power then on-net caches make complete sense and ultimately are more cost effective/better performing Paul > On Nov 18, 2016, at 1:55 PM, Ken Hohhof <[email protected]> wrote: > > Seems like there are many moving parts to this.
