SSL Certificate Renewal: Even Google Forgets
Apparently no one is perfect when it comes to renewing SSL Certificates. Google forgot to renew an SSL Certificate for www.googleadservices.com resulting in an error displayed on users' computers for a large part of the day.

This happens way too often, simply because it is an easy thing to forget. Late January, Yahoo forgot to renew their SSL certificate for the publisher network.
Andrew Codrington pointed out that Certificate Management services, such as the ones Entrust offers, can be a great help in avoiding certificate expirations like this. SSL Shopper also can send reminders about certificate expiration if you sign up for it using our SSL Checker.
