The attack is very large. The providers we have either can't deal with it, or my server with them is too small to deal with what gets through. I'm contacting them to see what can be done, if anything. I am also contacting two new providers I am familiar with to see if they can help expand our umbrella. All of our DDoS filters are European so I have to defer until the morning.

If that doesn't work, the next step is a literal build-your-own Cloudflare. The world is DDoS filtering as a service is very small an there aren't may options. The cost of entry is very expensive. If you're in that industry or adjacent and have thoughts about making it successful, or if you'd be interested in such a service, or something like a VPN service (which can sell excess bandwidth to help be profitable), email <josh@kiwifarms.net>.

We're still up on Tor.

Sorry there's not more good news.
