Start page is missing over time

Startpage of site missing sometimes on https://proto.actor/

A site that I configured today sometimes end up with a Netlify error screen saying “Page Not Found
Looks like you’ve followed a broken link or entered a URL that doesn’t exist on this site.”

Browsing the same site again some hour later and the start page appears again.

It id definitely hitting Netlify on the request as it is their error message about the missing page.

the strange thing is that if I do browse another page on the same site, it is correctly there.

e.g. requesting https://proto.actor/docs and the page is there.

What can cause only the start index page to not resolve correctly over time?

@rogeralsing Could you be seeing a local caching issue? The next time this happens, try visiting your site in a new private / incognito window, or opening it via GTMetrix. It seems unlikely that your page code is winking out of existence sporadically and then re-appearing.
