Bonus: the whole thing runs on a $5/mo FreeBSD droplet. Arc's performance is just that good.

I guess people really like toys written in arc....
You're right about the DDOS. Someone from the Czech Republic wrote a script to wipe the map. It briefly froze up the server.
I solved that by cloning the endpoint, disabling the old one, optimizing the new one, then rolling back the board by 1 hour. The scripter stopped.
If stuff like that keeps happening, I imagine we can fight it via cloudflare firewall rules.
