Re: Global caches

[Jeff Richmond <jeff.richmond () gmail com>]

While I would agree with that, having peering helps but certainly doesn't replace a localized CDN. Certainly better 
than nothing though. It also of course depends on the size of your network. If you are paying to carry that traffic 
(leased backhaul, etc.) from your peering point to your customers, you are still paying the same amount to deliver that 
content to your users (excluding any transit savings if moving from transit to get that CDN content). That is where an 
on-net CDN really saves you significantly as you can bury it deep into your network. I can't speak specifics here but I 
can tell you that the CDNs we have are filled at off-peak, so it really does become a win-win from a technical 
perspective (business case and politics are a completely different conversation though).
