> Dude, I’ve used 180 TB of traffic in one month on a 16$/mo server, and still, no throttling.

But legitimately using lots of bandwidth isn't the same as a DoS attack. Try and remember that bandwidth isn't the only resource being used.

In my experience they throttle your CPU usage after a while.

At no point did I suggest using Firebase was a good idea. I said it's always cheaper to run your own services in the long run, and that they'd have found out their own problems (see my first reply) sooner.

But my point is that you won't even ever have an issue with overusing traffic or CPU during a DoS, and the issue will be purely that your bandwidth will be saturated.

Vs. AWS, Firebase, etc where your limit will be your bank account instead.
