C6300 can't access some websites

Model C6300-AC1750

About 36 hours ago, I can access the internet, but get a 'can't connect to page' error on some websites.

Examples: these work:

Google

CNN

Facebook

I can't access these:

Mint

Bing

MSN

I've powered off and on several times.  I've also been in contact with my provider (Comcast) who tried a reset on their end (no help), checked a couple of other things, and then suggested I contact Netgear. 

I'd be grateful for any insight.

Thanks!

It could be a DNS issue that is happening. you may want to test this out and use Open DNS and see if anything changes.
