AT&T prefix flapping?

2009-10-16 Thread Jonathan Park
Hi all, For the past two months, it seems that AS7132 (SBIS-AT&T) announces and withdraws about 1,500 prefixes to AS7018 (AT&T) monitor every ~80 seconds. This observation is based on AT&T's monitor peering with RouteViews and RIPE. Does anyone know what's going on? Thanks, Jonathan
