For the past two weeks I have been unable to reach any of the CloudFlare primary name-server IPs. This includes 1.1.1.1, 1.1.1.2 and 1.1.1.3. I can reach the secondaries fine…
If I traceroute to any of these addresses, the exchange path appears to be going through Comcast in Mr Laurel NJ:

Any ideas? Could this be congestion in the exchange or something else?
