I don't think you are at all wrong; at this time Atrivo (AS) are still
announcing blocks in three Class B's that are assigned to other people:

        138.121.0.0/16  listed as       Ready Systems
        146.100.0.0/16  listed as       Zust-Ambrosetti (in Italy)
        170.208.0.0/16  listed as       Los Angeles County ISD

Here are the full current routing tables for those blocks ...

        138.121.16.0/21         10912           Internap
        138.121.52.0/24         16631           Cogent
        138.121.53.0/24         16631           Cogent
        138.121.56.0/22         16631           Cogent  ***
        138.121.128.0/19        26346 27595     Atrivo
        138.121.224.0/20        6939            Hurricane Electric

        170.208.0.0/24          16631           Cogent
        170.208.0.0/20          4474 27595      Atrivo
        170.208.6.0/24          16631           Cogent
        170.208.7.0/24          16631           Cogent
        170.208.8.0/24          16631           Cogent

        146.100.32.0/19         4474            NLayer
        146.100.48.0/20         4474 27595      Atrivo
        146.100.64.0/19         4474            NLayer

I have successfully pinged one IP in each of the blocks in that list,
so I am fully satisfied that all the blocks are live and being routed.

I personally telephoned Cogent's NOC two days ago to ensure they were
aware of the situation; I also attempted to reach Michael J. Hammons
(Sr. Director of Operations at Cogent) when no action was taken, but
was unable to reach him and my call was not subsequently returned.

I hope to have some helpful news of a short term remedy fairly soon.
