AT&T prefix flapping?

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
