  Here is what we have from DC (times are EDT, from )

Tueseday  : 6:00 AM - we saw 11617 ASN & 103978 bgp routes
Tueseday  :12:00 AM - we saw 11597 ASN & 103697 bgp routes
Tueseday  : 6:00 PM - we saw 11583 ASN & 103548 bgp routes
Wednesday : 6:00 AM - we saw 11566 ASN & 103321 bgp routes
Thursday  : 6:00 AM - we saw 11590 ASN & 103447 bgp routes
Friday    : 6:00 AM - we saw 11534 ASN & 103376 bgp routes

This is all the granularity I have, alas.

The Friday drop is due apparently to loosing 25 Broadway.
The Tuesday drop is slower and more complicated - 

Verio dropped 12 ASN by noon. Renater (AS 2200) dropped 32
ASN between noon and 6 PM. Other interesting ones lost 

AS  13619  BASELINEFINANCIALWTC (a sad AS name now).
AS  17087  NYSA 
AS  19072  OFFICEMAX    
AS  19073  DIGITRADE  
AS  19755  KIMBANET   

Some of these may have lost peering, some, such as AS 13619 and
17087, may have been taken out entirely.
