Re: IOS new versions and network load

[Paul Stewart <paul () paulstewart org>]

Apple does use CDN’s and does peer quite a bit as well..  What I have seen is our peering with Apple goes to a certain 
level of bandwidth and then spills over to CDN’s that we are either peered with or have on-net caches.  From our 
network perspective it’s simply a matter of ensuring there is enough capacit on the peering links and/or cache 
capacity.  If both of those options are exceeded then upstream transit starts to fill in the gap (only seen that happen 
once).
