I dunno what happened, but for the past four days I've been unable to access Blogger. And Google, and G-plus, and a bunch of other sites. Not all sites, just those with the https secure handshake. I use Firefox for my browser, and it seems that some change theymade affected how that worked. Https mark-up requires the host site to have a certificate. My browser looks up that certificate, and checks to make sure the site is real and secure. Some of the bigger sites on the Web, like Facebook, Google, Wikipedia, and more, somehow had certificates that the upgrade Firefox didn't like, and these pages simply wouldn't load.
Well, at least the problem has been fixed now.
