I’ve been to 8 different hotels in Singapore this past week, and the Cloudflare pop-ups have occurred at each hotel on their Wi-Fi (it doesn’t occur on my data plan as I am currently running on a Plus eSIM that routes back to Poland).
I question why Cloudflare thinks that all IPs coming from Singapore hotel WiFi (I’m not sure if all of these hotels have the same IP space, but they seem to have different providers, at least) are more risky than other IPs. Frankly, I have never seen this in any other country, and I can’t imagine that Singapore is a hotbed for DDOS attack origination or other malicious behavior due to the rule of law here.
