Long story short, my VPS, which I’m forwarding my servers through Tailscale to, got hammered by thousands of requests per minute from Anthropic’s Claude AI. All of which being from different AWS IPs.
The VPS has a 1TB monthly cap, but it’s still kinda shitty to have huge spikes like the 13GB in just a couple of minutes today.
How do you deal with something like this?
I’m only really running a caddy reverse proxy on the VPS which forwards my home server’s services through Tailscale. "
I’d really like to avoid solutions like Cloudflare, since they f over CGNAT users very frequently and all that. Don’t think a WAF would help with this at all(?), but rate limiting on the reverse proxy might work.
(VPS has fail2ban and I’m using /etc/hosts.deny for manual blocking. There’s a WIP website on my root domain with robots.txt that should be denying AWS bots as well…)
I’m still learning and would really appreciate any suggestions.
This is the most realistic solution. Adding a 0.5/1s PoW to hosted services isn’t gonna be a big deal for the end user, but offers a tiny bit of protection against bots, especially if the work factor is variable and escalates.
It also is practical for bots. It forces people to not abuse resources.
There are a lot of crypto which increase workfactor PoW to combat spam. Nano is one of them, so it’s a pretty proven technology, too.
I’m putting crypto on my website. However, I think it would be feasible to do Argon2.
