Intermittent 404's for documentation pages on https://distributed.readthedocs.io

See original GitHub issue

I was having trouble navigating through the documentation for this project because I kept getting 404’s. I thought the docs were producing bad links, but I finally realized that distributed.readthedocs.io sometimes returns 200 and sometimes returns a 404 for the same URL! I realize this probably is an issue for rtfd/readthedocs.org but reporting it here since it’s most likely affecting your user base and maybe you have some way to force a rebuild or escalate the issue.

Example of 4 http requests to the same URL – 2 succeed and 2 fail:

for i in {1..4}; do curl -I https://distributed.readthedocs.io/en/latest/locality.html; done
