Some initial results from the RIPE Atlas measurements. The main measurement is https://atlas.ripe.net/measurements/2048605 (All data is public, but it is about a 700 MB download for one days worth of data). Other measurements are: 2048609 for IPv6 and two reference measurements that target a stratum 1 server at the RIPE NCC (2048606 and 2048610) Just some raw python output. 2015-06-29: Total: 2592 Total weird: 82 Mode: Counter({frozenset([u'server']): 82}) Stratum: Counter({frozenset([u'invalid']): 43, frozenset([2]): 29, frozenset([3]): 5, frozenset([1]): 2, frozenset([2, u'invalid']): 1, frozenset([4]): 1, frozenset([u'unsynchronized']): 1}) Leap: Counter({frozenset([u'unknown']): 46, frozenset([u'61']): 35, frozenset([u'unknown', u'61']): 1}) Ref-id (stratum 1): Counter({frozenset([u'PPS']): 2}) I defined weird as anything that doesn't have leap indicator as no. Ref Id is only listed for stratum 1. 2015-06-28: Total: 2710 Total weird: 114 Mode: Counter({frozenset([u'server']): 114}) Stratum: Counter({frozenset([u'invalid']): 67, frozenset([2]): 32, frozenset([3]): 8, frozenset([u'unsynchronized']): 3, frozenset([3, 4]): 1, frozenset([4]): 1, frozenset([2, 3]): 1, frozenset([1]): 1}) Leap: Counter({frozenset([u'unknown']): 73, frozenset([u'61']): 41}) Ref-id (stratum 1): Counter({frozenset([u'PPS']): 1}) 2015-06-27: Total: 2714 Total weird: 117 Mode: Counter({frozenset([u'server']): 117}) Stratum: Counter({frozenset([u'invalid']): 60, frozenset([2]): 32, frozenset([3]): 13, frozenset([u'unsynchronized']): 8, frozenset([1]): 2, frozenset([3, 4]): 1, frozenset([4]): 1}) Leap: Counter({frozenset([u'unknown']): 74, frozenset([u'61']): 43}) Ref-id (stratum 1): Counter({frozenset([u'ACTS']): 1, frozenset([u'PPS']): 1}) _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
