Did Google forget to renew their certificate? - No
Here's what I get on all my Google accounts. Is this a joke?
Apparently Google did not renew their certificate and I have to define exceptions for all Google properties.
What's the point of having a certificate then?
Turns out (Thanks Ran) - My computer somehow went back several years in the past.
As a result, my date was not correct and Google's certificates were expired.
It's still strange that they were expired but who cares :)
