Re: Is my device supported by an MCC library?
I know about Akamai.
That's the source of all these videos and music my grand-nephew and his sister were filling my network with (when I shared it with them and their mother) :(
The issue might be more on the Akamai side: I assume they're synching during phases of low(er) load - typically during the local late night/morning. As synching is a sequential process, also depending on available bandwidth on both ends, there's always a chance you may fall into the "synch gap".
PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)
