The .pl zone is having DNSSEC validation issues because the configuration of one of the .pl name servers is out of sync with the other name servers and is returning invalid NSEC3 responses. We have attempted to contact the domain operator, but have not received a response. Comcast will be implementing a Negative Trust Anchor to allow the domain operator time to correct the issue. This will be removed June 28, 2012. Although we are utilizing a Negative Trust Anchor, the responsibility for properly configured DNS records lies with domain administrators.
