The website is working very slow, but I don't get any error.
I remember there was a same problem in 2017 bull run. That time I got error every minute.
It's a DDoS, I'm working on it.
And that was why Theymos decided to use Cloudflare.
With regret, I am (for now) admitting defeat on the DDoS front, and we will soon be using using Cloudflare to protect against DDoS attacks. This change is in progress, and will take ~24 hours for everyone to see.
Edit:
Got this error few seconds ago.
