Sysadmins slam Apple’s SSL/TLS cert lifespan cuts
(www.theregister.com)
This is a most excellent place for technology news and articles.
I was in a meeting before the summer discussing this with Digicert we asked if you would need to pay every 90 days.
They answered that certs will still be bought at 1, 2, or 3 year intervals but can be renewed for free every 90 days.
It's pretty obvious when you think about it really.
