I'm seeing issues with domains using domaincontrol.com nameservers. Some nameservers are answering queries. dig [ommited] @pdns01.domaincontrol.com. [ommited] IN A ;; ANSWER SECTION: [ommited] 3600 IN A 66.209.212.92 ;; AUTHORITY SECTION: [ommited]. 3600 IN NS pdns02.domaincontrol.com.

Is anyone else seeing issues with Level3's DNS servers? We got an alert our mail servers were down but mail is flowing normally, if slowly. Trying to resolve our domain names against Google's 8.8.8.8 and OpenDNS's 208.67.222.222 servers seems fine but 4.2.2.2 and 4.2.2.1 is spotty at best, failing to resolve in most cases.
I'm not seeing any problems with the Dallas-hosted 4.2.2.2:
