I recently got a notice from Google that in October 2017 Chrome V62 with show the warning "NOT SECURE" on all our web pages we have a input field for search. Since on most of our pages there is nothing that would require secure information I've never felt the need for HTTPS. Our class registration pages are secure but not the general information pages. The warning is going to scare people though. Are others upgrading their websites?
Yep, I got the same messages. Some of our sites use SSL and we've been talking about migrating all the rest our sites for a while now. I suspect we will be doing it rather than just talking about it sooner rather than later now. :\
We have started the move to make all our sites HTTPS. With our InCommon membership (paid by our State Chancellor's Ofice), we get free certificates, so there is no ongoing costs.
In 2014, Google said they give some SEO bumps to HTTPS sites. Also, HTTP/2, the new version of the HTTP protocol, may effectively require HTTPS.
So with all that, it didn't seem like a bad idea to be all HTTPS.
