The Google Internet Authority G2 is signed by the GeoTrust Global CA and the company informed users that it is aware of the problem, but it hasn’t provided any details on the problem:
“We’re aware of a problem with Gmail affecting a majority of users. The affected users are able to access Gmail, but are seeing error messages and/or other unexpected behavior,” states the Gmail status page Saturday afternoon.
When users’ email client (i.e. Microsoft Outlook) attempted to connect to smtp.google.com they received security warnings.
“This Certificate has an Invalid Issuer,” is the messagge displayed to the users.
Google immediately started the operation to fix the problem, at 3:46PM the issue has been resolved.
“The problem with Gmail should be resolved. We apologize for the inconvenience and thank you for your patience and continued support. Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better,” states the update issued from Google.
The Google Internet Authority G2 is now set to expire on Dec. 31, 2016.
