DNS servers configured to use DLV DNSSEC keys repository did not work correctly, because of the outage of DLV system on Sunday the 5th April, from midnight to 4 am. Due to a failure in a key roll script, the zone was improperly signed.
Better option than DLV system (operated by ISC consorcium) is recently launched ITAR repository. ITAR is based on different technical architecture making such kind of outage impossible. For more information look at IANA instruction page.
