Damn, you're getting similar levels to us. Got about 520k requests to the UIs in the past 24 hours (this excludes federation or app usage that hit APIs directly, I have Anubis placed after those are split off).
Of those 520k, Anubis flat denies about half. and virtually all the rest are challenged, with somewhere around 7% actually being completed. So we are talking about 18k of the 520k getting through now. Most of those are probably still bots (logged in users get a straight pass through, and as mentioned federation or app users don't follow this path), but the server is much happier now than it was a few days ago.
I have Cloudflare disabled now, trying that out. I've had to get Grafana up to scratch as I don't get to use Cloudflare stats to track anymore.
