Popular CA Let's Encrypt's original root certificate expires on 30th 
September 2021. Their issued certs autorenew, and are signed with a new 
root, however vendors were slack about picking up the new root, and there 
are a lot of devices that no longer receive vendor cert updates, so 
there's going to be certain amount of pain after the 30th.
