On October 30, 2008, Sprint Nextel severed its peering relationship with Cogent Communications due to a contractual dispute. A temporary repeering between the two providers occurred on November 2, 2008. Please note that this repeering is only temporary and outstanding issues between Sprint Nextel and Cogent Communications still need to be addressed.

As best practice, Internet Service Provider (ISP) diversity is recommended as stated in the NIST Special Publication 800-053A "Guide for Assessing the Security Controls in Federal Information Systems" Section CP-8. Organizations should ensure that critical mission/business functions are available through alternate telecommunications services if their primary service provider is unavailable.
