Yes, Jeff Ubois and I have been discussing it with Brewster.
There was significant effort put into this some eighteen or twenty years ago,
backed mostly by the New Zealand government… Called the “Internet Capacity
Development Group.” It had a NOC and racks full of servers in a bunch of
datacenters, mostly around the Pacific Rim, but in Amsterdam and Frankfurt as
well, I think. PCH put quite a lot of effort into supporting it, because it’s
a win for ISPs and IXPs to have community caches with local or valuable content
that they can peer with. There’s also a much higher hit-rate (and thus
efficiency) to caching things the community actually cares about, rather than
whatever random thing a startup is paying Akamai or Cloudflare or whatever to
push, which may never get viewed at all. It ran well enough for about ten
years, but over the long term it was just too complex a project to survive at
scale on community support alone. It was trending toward more and more of the
hard costs being met by PCH’s donors, and less and less by the donors who were
supporting the content publishers, which was the goal.
The newer conversation is centered around using DAFs to support it on behalf of
non-profit content like the Archive, Wikipedia, etc., and that conversation
seems to be gaining some traction. Unfortunately because there are now a
smaller number of really wealthy people who need places to shove all their
extra money. Not how I’d have liked to get here.
