Inquiry: Why is my custom domain going up and down with periodic "page not found" error?

Hi, @icarofr, that will depend on what the root cause of the issue is. To determine that, we’ll need more information to research this.

I would encourage you do collect this data locally as we might not see what you are seeing, even if we use a VPN to simulate our request from the same geographic region.

First, it is a DNS issue or a HTTP issue?

If the issue is DNS

If the issue is DNS, the following details would be helpful:

  • what is the custom domain name being used?
  • what DNS resolver is being queried?
  • what are the results of the DNS query?

If the issue is HTTP

For this, the x-nf-request-id HTTP response header (or the information it replaces) will be most helpful.

There more information about this header here:

If that header isn’t available for any reason, please send the information it replaces (or as many of these details as possible). Those details are:

  • the complete URL requested
  • the IP address for the system making the request
  • the IP address for the CDN node that responded
  • the day of the request
  • the time of the request
  • the timezone the time is in

To summarize, we will be happy to research this issue but we require more information in order to do so.
