dnssec-delegation seems to be broken from .gov to bls.gov

[Bhangui, Sandeep - BLS CTR]

The problem has been resolved.

The automatic KSK rollover on the dotgov.gov did not happen properly and once we manually updated the DS record with the correct KSK keytags and keys things were fixed.

All is good now.

Now to see if we can find out as to why the automatic KSK failover on the dotgov.gov did not happen correctly.

Thanks
Sandeep

I could be wrong, but based on the output above it looks like the current TTL is 0, which means that doing this should provide immediate relief.

Sorry it looks like the DNS server on the Wi-Fi network I'm connected to has done something weird with the TTL.

This is what I get when querying one of the "gov." authoritative servers directly:

$ dig -t ds bls.gov @a.ns.gov +norecurse

This means when you remove the DS record, it will take 1 hour to fully take effect (assuming no delay replicating between authoritative servers).
