Is this basically Archive.org becoming a customer of Cloudflare CDN to reduce load off their servers?
The next step would be for Cloudflare to point to Archive.org Wayback links when an origin isn't available (similar to browser extensions that point to Archive.org when sites 404 or are down, but in Cloudflare's core).
Cool stuff. Thanks Cloudflare folks.
It wouldn't be fair to use archive.org's community-sponsored resources for propping up businesses which are too cheap to pay for proper IT :)
