We had to deal with the sectigo / addtrust expiration. It was annoying because we reached out to our cert vendor and they had claimed it would not affect us (only affecting “legacy” systems or old browsers), but then of course it did affect us. It was an easy resolution, but still annoying.

Of course, we still have people working on our stuff. If it were some abandoned hardware product I could see this being a disaster.

We too were affected by the Sectigo / Addtrust expiration. Google's Uptime Checks couldn't verify the validity of the certificate and reported our website was down. While this was a false alert and it was easy to verify and circumvent it just shows that even companies like Google aren't prepared for something like this.
