SSL Expiration or Security Breach?

As of 4:49pm CDT today (May 16, 2017), the SSL license on expired and Google is warning me of an insecure connection. I was having lag issues with the Notable extension earlier this afternoon, and now I I am not sure if this is related to the latest ransomware attacks worldwide, or a legitimate SSL expiration. Is anyone else having this issue? I am hoping for a swift response, as Notable is a business tool I rely on daily.
