ARIN RPKI RRDP Service Disruption

ARIN’s RPKI Repository Delta Protocol (RRDP) endpoint experienced a service disruption on July 8, 2024. RRDP is the primary mechanism by which RPKI relying party software (validators) fetches updated RPKI objects from registries. During the disruption, relying parties were unable to receive fresh ARIN-region ROA data via RRDP, potentially falling back to rsync or serving stale cached data. ARIN published an incident report on their status page.
