Issues connecting to Cloudflare over IPv4 in Nashville

[Landy Bible <landy () ljb2of3 net>]

A client reported issues connecting to various websites this evening
and I've narrowed it down to cloudflare hosted sites specifically on
ipv4. My traceroutes go through my upstream all the way to Comcast in
Nashville where they die.

IPv6 cloudflare addresses work just fine, but several v4 addresses I
tested fail.

Is anybody else seeing similar issues, or anybody from cloudflare here
able to help me troubleshoot?

Thanks!
