IOS new versions and network load

Sun Sep 17 23:47:10 UTC 2017

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).
