Yup, 

Looks like they've started getting things a bit organized since sunday night/
monday early dawn. From my network's pt of view, you can see the sudden slight
"sink" in announcements transited thru UUNET which is where bellsouth's prefixes
come from on my end: http://www.twdx.net/bgp/graph-1w.png

More on this -

Two of BellSouth's AS's (6197 & 6198) have combined to inject around
1,000 deaggregated prefixes into the global routing tables over the last
few weeks (in addition to their usual load of ~600+ for a total of
~1,600).   

Kudos to BellSouth for taking first steps to clean this up 
overnight -- about 1100 of the prefixes left the table between 
about 01:45 and 03:45 GMT.  Very nice deflation. 

Next topic: multiple origin ASNs ..
