Again, it's probably _not_ Virgin's fault or responsibility. Capacity planning is handled by Google directly.

Also, I think that virtually every ISP with more than a few tens of thousands users is hosting a GGC instance nowadays (and a Netflix OpenCache, etc. etc.).

Nowadays, the vast majority of the transit&peering of ISPs is not going to the Internet, but to a few racks of local caching servers managed by OTT operators.

Bandwidth-wise, at least in prime time, the Internet is much less connected/realtime than people think :)

I would suggest that the deep packet inspection is Virgin's fault. Perhaps it was Google under provisioning the CDN inside VM's network, but I would suggest that's also probably Virgin's fault in part, as they will likely have more network information available to them that may have suggested network congestion, but that was not acted upon.
