Thanks for the follow-up. Unfortunately, I wasn’t able to reproduce the issue when originally responding to this post. I also haven’t seen similar issues during that time period, so I’m also not sure why it happened.
If you do run into this issue again, if you could provide a time frame and the X-Nf-Request-Id of the 404 that’ll help us look into the issue. This guide will assist with getting the request ID: [Support Guide] Netlify Support asked for the 'x-nf-request-id' header? What is it and how do I find it?
