Dang, I did not realize how much the 8 core nginx server was limiting performance of Infosec.exchange. I am really sorry. Should have noticed it much sooner.
Fedia.io remains problematic. I just found that my cron job that cleans up broken linkages between tables in the postgres database stopped working and so that's why the error 500's are back. I will get that fixed, but I have to tell you that I am wondering about the sensibility in continuing to run kbin on that instance. It's held together with tape and gum.
