alt Hacker News> That explains why one of my IoT vendors is using an expired certificate.
I don't think so. There was a dip in success rates for 90 minutes today, but nobody should be renewing their certificate within 90 minutes of expiration. If you're at that point, something went wrong weeks ago.
"nobody should be renewing their certificate within 90 minutes of expiration"
You obviously haven't worked with hardware guys.
"I mean, what's the point of those last 30 days if you need to renew it 30 days before expiration? Why not just renew it before it expires? If I'm required to renew it 30 days before the expiration date then the expiration date is a lie, isn't it?"
