wow, lots of akamai

I am going to disagree with your characterization of how Akamai - and many other CDNs - manage things. First, to be blunt, if you really think Akamai nodes are “sitting idle for weeks” before CoD comes out with a new game, you are clearly confused.
More importantly, I know for a fact Akamai has spent ungodly amounts of money & resources putting content precisely where the ISPs ask them to put it, deliver it over the pipes the ISPs ask them to deliver it, at precisely the capacity the ISPs tell them.
On the other hand, I agree with your characterization of residential broadband. It is ridiculous to expect a neighborhood with 1,000 homes each with 1 Gbps links to have a terabit of uplink capacity. But it also should have a lot more than 10 Gbps, IMHO. Unfortunately, most neighborhoods I have seen are closer to the latter than the former.
Finally, this could quickly devolve into finger pointing. You say the CDNs bear some responsibility? They may well respond that the large broadband providers ask for cash to interconnect - but still require the CDNs to do all the work. The CDNs did not create the content, or tell the users which content to pull. When I pay $NATIONAL_PROVIDER, I expect them to provide me with access to the Internet. Not just to the content that pays that provider.
Personally, I have zero problems with the ISPs saying “give me a cache to put here with this sized uplink” or “please deliver to these users over this xconn / IX / whatever”. I have a huge problem with the ISPs blaming the ISPs for delivering what the ISP’s users request.
Of course, this could all be solved if there were more competition in broadband in the US (and many other countries). But that is a totally different 10,000 post thread (that we have had many dozens of times).

It's just not economically reasonable to expect that. Remember we're talking about residential service here, not enterprise circuits.

That sounds easy, but there are plenty of legitimate reasons why ISPs can't or don't want to do that, particularly for an event that only occurs once per quarter or so.
> Does Akamai bear some burden here to make these rollouts less troublesome for the ISPs they traverse through the last mile(s)? IMO yes, yes they do. When you're doing something new and unprecedented, as Akamai frequently brags about on Twitter, like having rapid, bursty growth of traffic, you need to consider that just because you can generate it, doesn't mean it can be delivered. They've gotta be more sophisticated than a bunch of servers with SSD arrays, ramdisks, and 100 gig interfaces, so there's no excuse for them here to just blindly fill every link they have after sitting idle for weeks/months at a time and expect everything to come out alright and nobody to complain about it.
