As you noticed, I had to temporarily enable DDoS protection. Someone is trying quite effectively to distract me from my activities ;p Unfortunately, this may cause some issues with the federation. I will try to cut off the traffic as soon as possible and return to normal operation. Thank you for all your support and patience! :)
@ajar7 Yep, I saw it that way, and it seemed to be going quite well. That changed a few minutes after I posted the screenshots and server specifications :) Perhaps it’s just a coincidence, but it was a huge change in such a short period of time. I still want to verify this and have external confirmation, but DDoS protection is currently the only option to keep the website alive.
