Your modem is fine and firmware version 10.01.03 is the most recent. Xfinity is in the process of slow rolling activation of their Enhanced Speed Network area by area. It may take a few months for completion.
Agree with michaelkenward this points more to your router than your modem. There is a chance Xfinity has some problems with a group of WAN IP address it is using.
Suggest you change the Domain Name Server configuration in your router. Try using some of the public servers from Next, OpenDNS, Cloudflare, Google, etc. to see if the problem goes away.

I'd agree with checking your router and its DNS settings. Don't just check/change the IPv4 but also the IPv6. Might be why some are showing correct and others aren't.
