[afnog] Weekly Routing Table Report

[Frank Habicht]

Hi,

is someone from Sudatel AS15706 on this list?

(almost) the whole Internet sees /29s and /28s from one of your BGP
customers.

The one that can change from 43 to 4 prefixes announced without loosing
anything.

Frank
slightly shocked.

PS: oh, I just see you're also mentioned below....
