Seems the entire .biz tld is failing DNSSEC validation now. All of my DNSSEC validating resolvers are tossing all domains in .biz. The non-signed domains too of course because trust of the tld itself cannot be established.
So which event caused more disruption? 50K .com's in a failed DDoS mitigation, or every single .biz lookup by something that actually does dnssec?
I don't think we are trying to quantify which one was worst or point fingers at, but how do we remediate these type of issues in the future? I think these events will happen more and more often... a TTL of 2 days seems rather long for NS and do I see 6 days TTL for DNSSEC records for .biz ?
