For the past two weeks I have been unable to reach CloudFlare's primary name-server IPs 1.1.1.1, 1.1.1.2 & 1.1.1.3. The secondaries which use a seperate prefix are reachable.
If I perform a traceroute to ANY host IP in the 1.1.1.0/24 range, the last hops I can reach are a Comcast host IPs registered in Mt Laurel NJ. It appears that either Comcast is using these addresses (shame on you) or its a routing issue in NJ.
If anyone from Comcast is monitoring these threads, can you please look into this?
