I Recently Purchased Flaunt 7.. Seems Good Overall... But 2 days ago there was a downtime of 2 Hours.. When Contacted Support .. they Said they were Getting Attacked

Yup, I can confirm they were down a few days back too; on their WHMCS don't even have server control options.
I have the following configuration for a client (file sharing with high DMCA rate) site, and I'm not worried about downtime or even, data lost, with these "DMCA ignored" hosts. I'm not saying they're unreliable or what, but surely not as good as the big boys (AWS, GCP, etc) in the market. So here's it in case anybody looking for similar setup.
[User] ---> [Internet] ---> [Cloudflare Proxy] ---> [Flaunt7 Reverse Proxy] ---> [GCP NL] ---> [etc, etc, etc]
1) Cloudflare is proxied to f7 server. This way, the content author sends DMCA to CF and request them to forward it to hosts (in this case, it's not even f7, it will be the owner of the ip-block; not going to reveal who), it will be ignored.
2) Flaunt7 server is installed with Nginx and configured it as reverse proxy with proxy_pass to IP address of the GCP NL server, which is the closest to f7 with lower latency (about 30ms).
3) GCP NL, your usual LEMP setup with virtual host and create a default_server and null route it. So there's no way to http access anything via ip or hostname except the virtual host, and virtual host is proxied from cf to f7.
Do note that you will need to pass cf-connecting-ip in f7 and then set real_ip_header from f7 in GCP NL; otherwise you'll get your reverse proxy IP for all the visitors at the site.
Feel free to drop me a PM if you need help, and I will reply when I have time.
