Change in DNS servers - problem resolved

Yesterday, whenever I tried to load any page from the Internet, I was confronted with browser warnings that it received a certificate that it did no trust.

 

This certificate was issued from register.be.xfinity.com. No matter where I went with SSL, I encountered this. I checked my firewall settings and found that as a DHCP client it received new DNS servers:

 

162.150.8.51 -> susilanding-chic-vip.sys.comcast.net

162.150.21.51 -> susilanding-denv-vip.sys.comcast.net

 

I've always previously received

 

75.75.75.75 -> cdns01.comcast.net

75.75.76.76 -> cdns02.comcast.net

 

I changed back to the 75s locally on my firewall and resolved my problem
