[outages] Level3 DNS Servers down?

[Andres Herrera]

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.
[ommited]      3600    IN      NS      pdns01.domaincontrol.com.

dig [ommited] @pdns02.domaincontrol.com.
