If you haven't already seen it, the great Todd Underwood of Renesys published an article today on his blog regarding this subject: http://www.renesys.com/blog/2008/10/wrestling-with-the-zombie-spri.shtml An aside, WV Fiber (AS19151) is currently partitioned from Cogent since AS19151 only contracts with Sprint for transit and is settlement-free with the rest of its peers. As previously reported, late last year, Cogent depeered AS19151 for unknown reasons. Up until yesterday, this wasn't much of a problem. Now unfortunately, the two networks (AS19151 and AS174) are partitioned. Any single homed WV Fiber customer and any single homed Cogent customer can not reach each other. WV Fiber hosts over 7 million eyeballs and many networks under its AS. We hope Sprint and Cogent work out their differences, but in the mean time, we unfortunately will remain partitioned from Cogent. Regards, Randy Epstein President WV Fiber
