ISP's await iOS launch on Sep 18th.

One of those lovely occasions when ISPs get a good test of their networks capacity when hundreds / thousands / millions of customers test their network with a rather large update being released causing large volumes of traffic.

With CDN the traffic tends to be more distributed and localised but it still is rather interesting to watch.
