Given that the expiry is now less than a month away, I felt there was a need for some obligatory countdown page you can stare at and get mesmerized. Since I couldn't find one, I quickly hacked one together (very limited effort on my side, improvements welcome).
I'll use it as a night light!
I don't know what emotion to feel in this moment but the countdown itself sure made me laugh!
Styling on mobile is somehow broken right now... It worked like 20 mins ago. Now I remember why I never wanted to work in web design.
Edit: Apparently fixed it.
By fine, I mean it looks like a properly-formatted doomsday clock...
mesmerized.
mesmerized..
Needs a Dark Mode.
I'm still a little nervous that windows is going to smoothly handle the R3 changeover..

There is already a perfectly good "in case of emergency break glass" workaround option in the plan:
[Temporarily switch to another FREE CA until this gets resolved permanently]
Given: There may be the production hit taken.
So, for the super fearful, maybe the preventive measure is to implement the workaround just before the expected possible impact. And switchback after the all clear has been sounded.

But how will I...

Ha yeah, I'm keeping that one in my back pocket but unfortunately I actually can't contact 96% of my users because I don't collect their email address - short sightedness on my part! I wouldn't want to scare them anyway especially as it should all go off without a hitch.
Prepare the ALERT PAGE
Oeehh, nice!
Can't we have this countdown at the top of the Community? Like just as the disruption banner?
Pleaaasseeee? Looking at @jple here
That's just wicked, @Osiris.

This is now added. Automatically set based on what the browser indicates is the user preference.
An ominous font paired with an occasional glitch in the countdown would really up the fear factor.
Still looking into some magic fancy things for when the countdown reaches the magic value. Sadly my CSS skills are limited.
Probably when the countdown is done, the site should just change to an emulation of the browser's "this site can't be verified, are you sure you want to continue" page.
Encryption is now OFF
All of your personal information (and questionable browsing habits) might be publicly exposed.
I find it funny that some systems (and people) would rather use HTTP than HTTPS with an expired certificate in the chain. It's not like RSA (or EC or whatever) selectively and suddenly stops working when a certificate expires.
