remarks:        The BGP Clock
remarks:        
remarks:        Every 1 hour the prefix 147.189.(216+N).0/24 is advertised. The
remarks:        N here is calculated as HH % 8, so the hour in 24h format
remarks:        modulo 8. Naturally, UTC is used. The prefix is withdrawn 10'
remarks:        after the advertisement.
remarks:        
remarks:        At most one /24 should be available at any single time, which
remarks:        means that all 8 prefixes of the /21 rotate 3 times a day.
remarks:        
remarks:        At 00:00, 147.189.216.0/24 is advertised, at 00:10 it is then
remarks:        withdrawn, then at 01:00 147.189.217.0/24 is advertised, which
remarks:        is in turn withdrawn at 01:10, and so on.
remarks:        
remarks:        Why? We are conducting research on BGP Stuck Routes to better
remarks:        understand how they happen, when, which equipment is more
remarks:        buggy, etc. We also want to understand them better. As this is
remarks:        a beacon, anyone can study the results using RIPE RIS, or any
remarks:        other source like RouteViews. Feel free to take a look and let
remarks:        everyone know if something interesting ever comes up!
remarks:
