AWS S3 Expiration issue
Almost all the images live in AWS S3. Many of these URI tokens expire 1 hour after being generated. A link can be checked whether it's expired because the Expired parameter is a timestamp after which it will not longer be valid. Where this is particularly problematic is the thumbnail URLs. Any webpage that contains a thumbnail image, those images need to be grabbed in the next hour or will be missing and can not be repaired later.
Saving with the internet archive
Saving urls with https://web.archive.org/save/ actually works great, even though it looks like it fails.
The page will always show "404 Not Found", such as this random example.
But the page html contains: \"imageUrl\":\"https:\u002F\u002Fsketch-cloud-storage.s3.amazonaws.com\u002Fac16b85e-f285-44f3-ae2d-4c3ccdc1f413\u002F2ad6cf73-41f7-4048-aa2f-2eaca80b1ebc_s?AWSAccessKeyId...
And that link works, at least as a prefix search: https://web.archive.org/web/*/https://sketch-cloud-storage.s3.amazonaws.com/ac16b85e-f285-44f3-ae2d-4c3ccdc1f413/2ad6cf73-41f7-4048-aa2f-2eaca80b1ebc*
In fact, it gets both png ang jpeg formats!
We saved a random sample of about 50,000 pages (in addition to whatever the real code has saved).
There might be 18 million pages (the /feed/global/list/ urls seemed to run from about 180817470 to about 199228198)? If true, we saved 1 in 300 images.
