What's wrong on my end? I get this from both Firefox and Chromium:
Firefox: Firefox detected a potential security threat and did not continue to amasci.com.
Chromium: https://amasci.com/weird/unusual/e-wall.html
Now "isdownorjustme" tells me amasci is down: https://downforeveryoneorjustme.com/amasci.com?proto=https
I'm not too sure what's going on.
You likely have HTTPS-only mode enabled in your browser(s). amasci.com doesn't have HTTPS configured and serves a certificate for (.*)eskimo.com. If your browser automatically rewrites all HTTP links to HTTPS, it'll throw these errors.
Try manually replacing https with http. Disabling HTTPS-only mode (or HTTPS Everywhere, or whatever is causing the rewrites) might also work.
