Everyone of these prefixes have managed to average one update per 40 seconds during a week, or worse. How is that even possible? Yes, I know we don't generally have dampening anymore, but geez, that's a lot of updates.

In the case of Cook Islands Telecom the problem is not directly with them - its their one-up upstream Spark NZ (AS4648) who appears to be flicking this route across a number of transit upstreams (http://bgpupdates.potaroo.net/cgi-bin/per-prefix?prefix=202.65.32.0.21) Geoff
