If you look at the 09/19 and 09/26 CIDR Reports, BellSouth Atlanta (AS6197) did something similar during this time period -- they added about 350 deaggregated prefixes, most if not all /24's. > Usually when we see deaggregations, they hit quickly and they > disappear quickly; nice sharp vertical jumps in the table size. > This event lasted for hours and, more importantly, the prefixes > haven't come back out again, an unusual pattern for a single-origin > change that effectively expanded global tables by half a percent. That AS6197's additions are still present isn't encouraging. -Terry
