On Nov 20 at 9:48PM EST (UTC-5), we were notified by a 3rd party that validators no longer were fetching ROAs from organizations that had selected the delegated option.  Upon review, ARIN Engineering discovered that a certificate was not included in the manifest for each delegated organization. The fix was to include that certificate in the manifest for each delegated organization was deployed at 1:20AM EST (UTC-5) on Nov 21.  At that time, ROAs from the affected delegated repositories could then again be fetched and validated.

ARIN has nine delegated organizations and affected approximately 180 ROAs that may have disappeared from the global RPKI system for approximately 35 hours and 40 minutes starting on Nov 19 at 2:30PM EST (UTC-5). Depending on how validation is setup by the ISPs who use RPKI, the route origins associated with these 180 ROA’s may have remained in the secure state or became unsecure during this period.

I think 'unknown' and maybe (if there were ROA for supernets possibly
invalid :( oops.

Do you all document what is tested? so either RP software folk can
integrate similar tests (or suggest others), and/or so actual ARIN
users of the RPKI can test their (or instrument their) repository
