That's interesting. Once, a few years/jobs/etc ago, I observed a flow from mobile youtube being really really bursty, peaking to a 40-50mbps on a 10mbps circuit, but that was the only time I've ever seen such an issue. After that one flow died, it never happened again.
That aside, I do work for a business-focused mostly-wireless SP at the moment and I haven't had any issues with CDNs so far. The only similar incidents I can recall involved customers running programs like aspera and signiant which, when misconfigured, can result in quite some volume coming your way.
