Example URL:
https://stevereads.com/cache/ephemeral_web_pages.html

Steps to reproduce the problem:
1. Try loading a page that has disappeared from the web.
2. See a clever or generic 404 page that doesn't help you find the content.
3. Weep a single tear for the silent disappearance of a piece of our culture.

What is the expected behavior?
Offer to try to find the missing page on archive.org's Wayback machine if it is indexed there, or in Google's cache.

What went wrong?
