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.
