Most succinct yet informative possible description of IsThereNet, I think :)

u won’t

I am so installing this! Will be very useful beyond the simple use case in my OP. Thanks Data.

Clever! Thanks for finding those links too.

Ah, my threat model isn’t that Snowden, thanks.

you could get a false negative

Good point. Will keep that in mind in general. (For this specific use case? Maybe it’s fine since if I see the red bar while my apps are still working, I could ignore it - but now I’ll think back to your comment and understand maybe Cloudflare is experiencing an issue. In which case I’ll check their status pages and wouldn’t be surprised to see some news article or complaints too!)

Thank you, and thanks for the counterpoint @TaviRider@reddthat.com

In 2004 I would not have understood why!

Naughty naughty 🙂

Good alternative, thanks!

Neat - thanks. Looks like one could use the following, but not necessary:

208.67.222.222  
208.67.220.220

Thanks for the explanation and easily digestible analogy :)

Thanks everybody!

(1) ICMP (Internet Control Message Protocol) Echo Requests hardly constitute a burden on a server.
(2) There is little privacy concern simply exposing your IP to Cloudflare.
(3) Uptime-Kuma can be self hosted to accomplish this task with more bells and whistles.
(4) There is an appetite for daydreaming of DDOSing bad Alphabetic actors ;) You civilly digidisobedient rascals!
