i think the cogent depeering thing is a myth of some kind

at <http://www.e-gerbil.net/cogent-t1r> there is a plain text document with
the following HTTP headers:

	Date: Fri, 28 Sep 2007 21:56:34 GMT
	Server: Apache/2.2.3 (Unix) PHP/5.2.3
	Last-Modified: Fri, 28 Sep 2007 19:15:53 GMT
	ETag: "92c1e1-a85-43b36ea5bcc40"
	Content-Length: 2693
	Content-Type: text/plain

the plain text title is:

	Cogent shows hypocrisy with de-peering policy

the plain text authorship is ascribed to:

	Dan Golding

the first plain text assertion that caught my eye was:

	Cogent, has, in fact, de-peered other Internet networks in the last 24
	hours, including content-delivery network Limelight Networks and
	wholesale transit provider nLayer Communications, along with several
	European networks.

since i appear to be reaching the aforementioned web server by a path that
includes cogent-to-nlayer, i think this part of the plain text is inaccurate.

the second plain text assertion which caught my eye was:

	Why is this happening? There are a few possibilities. First, Cogent
	may simply want revenue from the networks it has de-peered, in the
	form of Internet transit. Of course, few de-peered networks are
	willing to fork over cash to those that have rejected them. Another
	possibility is that Cogent is seeing threats from other peers
	regarding its heavy outbound ratios, and it seeks to disconnect
	Limelight and other content-heavy peers to help balance those ratios

this makes no sense, since dan golding would know that cogent's other peers
would not be seeing traffic via cogent from the allegedly de-peered peers.

so, i think the document is a hoax of some kind.  (i saw it mentioned here.)
