OK -- nothing to see here!
In case you are using firefox and your request was for http://grail.smcs.upei.ca, but you were "upgraded" by firefox to https://grail.smcs.upei.ca, you can make the following change(s):
about:configsettings like
browser.fixup.fallback-to-httpsto false or
network.stricttransportsecurity.preloadlistto false. To do that, you type
about:configin you address bar and after the page is loaded and you accept the risk, search for the fields to be modified, and change their default value. You can also manually type the full http:// address or use an add-on like HttpRequester.
