Is there anything related to DoS / DDos and rate limiting websocket requests? I also found not much in the forums on this, besides The Missing Link in Meteor's Rate Limiter (which was also by @pcorey)
I basically want to lock out users that exceeded the limit using nginx instead of using the software layer. But I am still unsure how to keep the bridge from my Meteor Environment to my nginx config.
I could just add IPs to a blacklist using fs and let nginx use this file to know when to lock-out IPs but this gives me somehow a bad feeling. And using services like Cloudflare are unfortunately an anti-requirement in my projects 
Any suggestions on that in the book or anything planned @pcorey ? Since you opened the linked forum thread I’d like to know how you solved it in the end.
