lets see, should we be concerned? here are a few interesting tables, the 
cnt column is new IP addresses we have seen in the last 5 days. The 
first table is Tier-2 ASNs as classified by Fontas's ASN Taxonomy paper 
[1] The second table is Universities. The ASN concerned are just in the 
announced by orgs in USA as to imply that they should be on NANOG.

Let me say it again the counts are NEW observations in the last 5 days. 
also note I'm not Gati, and I've got much more data on everyones networks.
