This was the issue yesterday. Overwhelmed the resources and caused the issues. Had to implement Cloudflare's system to stop the fake traffic, and then, after doing some digging, made a change last night that should hopefully help moving forward.
This should also solve some of the issues @n1997y mentioned, and should improve the performance a little bit. I've noticed things are a little quicker after the adjustment I made, so hopefully that's the case for everyone else.
