I’ve been troubleshooting an issue with a webserver locking up at seemingly random times. I am looking at the apache log and find tens of thousands of hits from Cloudflare-Traffic-Manager trying to GET a file named /healthz. The server is responding with a 404 error code. I do use CF’s DNS for one of the domains that point to this site, but nothing else is enabled on the account. The log gives a pool-id but I don’t know if its appropriate to post that publicly.
Assuming you haven’t created any health checks yourself on Cloudflare, you’ll have to create a support ticket at https://dash.cloudflare.com/?to=/:account/support and include the pool-id in the ticket.
Support will be able to find the associated health check with that ID and take further action if needed.
If your ticket gets automatically closed due to you being on the free tier, just post the ticket ID here, and we’ll escalate it so it gets re-opened.
