Cogent is experiencing two problems right now. Their automated message reports that they have a backbone problem causing latency, but they also seem to be experiencing peering problems with Sprint.
Are you sure that this is not in Sprint, or even Duke Energy ? I can't ping to 192.234.122.137 from either home or work, and I don't see any signs of Cogent problems from Tyco Road / Tysons Corner.
