It looks like Sprint has re-connected to Cogent for the time being, but Sprint has put out a fairly agressive press release. After seeing both sides, I have no idea who’s right, and it certainly looks messy.
For those that are interested, here are a couple of links:
Cogent’s original press release (expand Oct 30): http://www.cogentco.com/us/news_press.php
Sprint’s rebuttal and temporary reconnection notice: https://www.sprint.net/cogent.php
I’m still hoping the FCC will step in. Situations like this can only be messy and will probably continue to get worse if a precedent isn’t set.
