I’m located in Salzburg/Austria. My nearest colocation center always was Vienna.
Since a view days I see that the colocation center changed to PRG.
To Vienna, I had ~22ms ping.
To PRG, now I have ~33ms.
Deleted screenshots and debug info.
Since about 10 minutes, my colocation center is VIE again.

Cloudflare is an anycast network, so where you are routed is determined by peering with ISPs. The shortest path geographically isn’t always possible due to peering agreements.
If you request a site hosted on Cloudflare from home:
The domain resolves to a Cloudflare IP
Your browser sends an HTTP request to that IP
Your ISP’s routers consult their routing table and route the packets upstream to their transit provider ( COSTS MONEY )
The packets …
Also, PRG is only 20 kilometers farther than VIE
