Thank you for your efforts, work and results. Those "attackers" only deserve disgust.

Benefit of using Cloudflare CDN:
Commenting and editing took about 0.5 seconds!
Also, ping is now from 200-300 miliseconds to just between 50 and 60 (depending on your ISP):

The bugs in Lemmy are such that you don't even need to touch a server for it to be vulnerable. Cloudflare does not defend against such mistakes. Other servers can trigger deep PostgreSQL logic problems within Lemmy. Growing pains, a lot of the federation code was never tested, and today's crash is due to a logic issue with lemmy_server mistakenly updating 1700 servers it knows of through federation for a delete instead of the 1 local server.
I'm learning a lot by following lemmy.worlds actions. Appreciate the transparency!
I hope lemmy.world can avoid using Cloudflare which goes against the spirit of Fediverse as it's just an objectively evil company.
Agreed. This is an emergency fix. Will look for final solution later.

The more you attack a Lemmy instance, the more stronger it gets.
It's like tempering iron or steel.

It's not ideal, but there's not a whole lot of options out there for DDoS mitigation.

I put this site behind cloudflare in response to this post. Other than having to change SSL/TLS encryption mode to Full, it seemed easy. I turned on bot fight mode and I'm using the managed WAF ruleset that comes with the free tier. Any configuration recommendations anywhere in the panel?

Welcome to the internet, glad thereβs a working solution
Damn these script kiddies.. I don't like Cloudflare at all but it does its job well. It may just be my paranoia, but putting a single entity in control of so many websites seems dangerous. I think we have all learned about the intentions of big corporations. But hey, it's better than being taken down tbf.

Hmmm, we're getting a fuckload of web requests on our Lemmy too... I think I'll enable CloudFlare too! :)

I wonder now with the semi-adversarial/semi-cooperative nature between lemmy instances, if wer'e not going to see more DDOS and other types of raids happening because a different instance has an ax to grind against yours. Say between you defederated them, or they consider your instance too big etc.

Maybe is that Reddit dude, jealous of Lemmy's increasing popularity.
It seems like you made this comment in jest, but I wouldn't say it's outside the realm of possibility. We can't fly off the handle and lob accusations absent any sort of proof, but it would hardly be the first example of a corporation targeting an up-and-coming disruptive service run by amateurs.
