Comcast "SIBCN.COMCAST.NET" Security Certificate Expired

In Comcast e-Mail, I get the message the "SIBCN.Comcast.Net" security Certificate has expired as March 1, 2016.    It is amazing the  youngsters servicing IT in Comcast would let this happen to its customers.  


After 45 years in IT, I see in the 21st Century there is a definite lack of detail in IT these days.    Are there any bets how long this will be outstanding.  I figured a few days ago, it would be top priority to get fixed.  I see in forums this happened in 2012 (sounds like a 4 year certificatewas gotten) and it took 3+ months to resolve.
