In terms of open connections, it varies, but right now it's 5k active connections. But there are many many self-hosters out there, and the people using Firebase (no "instant delivery") are also not counted in that.

You can subscribe to the stats above using the https://ntfy.sh/stats topic (old messages are only cached for 12h, so half the day it shows up as empty)

Thanks. I'll keep an eye on it. I have a lot of rate limiting in place, but for static resources it could probably be tighter.

Thanks this is really nice. Impressive to see that f-droid is that high!

Any protection against DoS in place, like WAF? Public services on EC2 are very prone to this kind of exposure. Maybe some fail2ban?
