    Cox is completing a Network Upgrade across all markets at various times to improve network reliability and increase bandwidth. The Network Upgrade includes the following work. Please check the link for more information www.cox.com/residential/network-upgrades.

      I was notified that the upgrade in our neighborhood was completed.  So this is probably not related to the upgrades, right?

      After trying the link that you provided for the network-upgrades, I see that the work can take up to 60 days!  By the way, the link needed to have the .html extension for it to work.

      Thanks for your input.
