Interesting. I’ve never seen that on an AT article before. The articles elsewhere on the AT home page all come up properly; just that one about the FDA is returning that error.
A Google search for “FDA takes down its propaganda demonizing ivermectin as a treatment for Covid” only returns THIS thread on FR, nothing on AT. It is not archived on the Wayback Machine.
try another search engine such as bing or brave or yandex
