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:	listed as	Ready Systems	listed as	Zust-Ambrosetti (in Italy)	listed as	Los Angeles County ISD

Here are the full current routing tables for those blocks ...		10912		Internap		16631		Cogent		16631		Cogent		16631		Cogent	***	26346 27595	Atrivo	6939		Hurricane Electric		16631		Cogent		4474 27595	Atrivo		16631		Cogent		16631		Cogent		16631		Cogent		4474		NLayer		4474 27595	Atrivo		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.
