Are they > multi-homed? Single-homed /24 through UUNet's 7046 to 701. Withdrawals started at 01:21:38 GMT (21:21:38 Eastern time), and ARIN flapped severely for about fifteen minutes. Then they spent another hour and ten minutes inconsistently reachable from half the world, with the picture mutating slowly. 701 seems to have been telling inconsistent stories about ARIN's reachability, depending on which of our peers you consulted -- IGP instability? By 03:10 GMT everyone seems to have slowly gotten a consistent picture again, with ARIN restored. AS7046 advertises 320 prefixes, of which ARIN is but one. Others (126.96.36.199/16, 188.8.131.52/16, 184.108.40.206/24) had even worse problems in the same timeframe. My guess would be the collision of two maintenance windows -- a simple problem on ARIN's end at the wrong moment, with global convergence severely prolonged by one of the UUNet BGP tummy-rumbles that we commonly hear in the middle of the night. Some of the little UUNet ASNs with 701 upstream can be really noisy -- 816 was rocking all night long. ---------- James Cowie Renesys Corporation firstname.lastname@example.org
