At 13:00 EST (UTC-5) today (13 NOV 2025), ARIN began restricting access to the 
sites that serve the ARIN Resource Public Key Infrastructure (RPKI) Hosted and 
RPS (hybrid) repositories. At 13:30, all access to the RPKI repositories was 
administratively blocked, simulating a full repository outage. At 14:30, access 
to the repositories was restored. Full redundancy of RPKI services was 
confirmed at 14:35, and the RPKI system returned to pre-test levels at 14:50.

This decision to conduct the test in ARIN’s production environment was 
carefully considered. Testing outside of production would not have provided an 
accurate representation of performance and preparedness for repository failure 
conditions. Therefore, ARIN chose to simulate this scenario in a live 
environment to best evaluate real-world impacts and response.

We appreciate the patience and cooperation of the RPKI community throughout 
this exercise and conduct this testing as part of our commitment to 
high-quality RPKI services.
