Is my website's performance degraded because of CDN?

If not an maintenance window such as planned for 07.10.2024.:

It’s unfortunately due to the ISP peering of the end-users visiting your Website. If you’re on a paid plan, it might get routed through some more priority location, however Vienna, Austria - (VIE) is mostly for :croatia: and :serbia: as far as I’ve experienced.

See my case when I switched my ISP:

Might have to cross-check with SOX peering matrix for such case, while the end-users can check via example.com/cdn-cgi/trace to see through which colo they’re connecting to.
