And to elaborate for some newcomers... this sort of thing has happened before, if I remember correctly it is possibly a yearly thing where the site's certification or whatever it is expires and doesn't get replaced or renewed (or whatever, I don't really know how this stuff works) for a few days or weeks (I don't think it has been longer than a month), and then eventually it gets renewed and goes back to normal. Been like this for a few years at leastThe old website is still up, you just need to press a button labeled advanced and then click a link that shows up labeled "Proceed to www.americanhistoryusa.com (unsafe)". It still works completely fine and I'm pretty sure nothing bad happens.
