Those of you using curl to grab things from my site should have a better time of it as of a few minutes ago. What happened? Well, a 20 year old cert from AddTrust that was in the chain finally expired. Firefox and friends don't care, but curl sure does!
Clearly, not everyone checks cert chains the same way.
Of course, if for some reason your path to trusting my cert was THROUGH that now-expired cert, the site now seems rogue. So there's that.
