e noticed SSL warnings based around Akamai's "a248.e.akamai.net" certificate today. NET::ERR_CERT_COMMON_NAME_INVALID is the most common error we're seeing. Can anyone comment on what may be going on? Looks like the cert was renewed or issued on 8/27/2015. Wonder why we are noticing the errors from multiple points on the internet now?
This is how Akamai has handled non-SSL customers for the last 15 years. It is the same error message, and the same action. You just noticed it. If you use https for a non-SSL customer on Akamai, you will connect to a Akamai server using a "default" SSL certificate for all customers on port 443. If you use https for a SSL customer on Akamai, you connect to different IP addresses listening for specific customers which return a customer specific SSL certificate.
