If you’re seeing a timeout when running the same command from the affected location, it would be a good idea to run a TCP MTR towards this IP to see whether the packets are dropped and on which hop this is happening: Gathering information for troubleshooting sites · Cloudflare Support docs.

Here is an example:

mtr -P 443 -T -r -n
