In autonomous systems running bgpd(8) and rpki-client(8) on their edge routers, it may be beneficial when out-of-the-box all routers don't all do rpki fetches & bgp loads at the same time. It is expected behavior for RPKI information to un-evenly percolate towards the BGP edge in a staggered way. The 'once an hour' pace may be a reasonable balance between the needs of internet users, and what network operators tolerate in churn. OK deraadt@OPENBSD_6_7
