Got confirmation from my Sprint service manager that there's a fairly major cut. I quote,
"Currently, Sprint has been impacted by a major network event (fiber cut) on the West Coast. This fiber cut has impacted both data and voice services. I will provide updates ASAP...."
This was followed up about 8 minutes later with, "The fiber cut occurred outside of Phoenix. The fiber techs should have arrive at 4pm CT."
More updates from my contact at Sprint and there's some interesting factoids in here: "There are some locations east of the Rockies that are experiencing issues. Sprint network control centers have multiple bridges activated and are exploring restoration opportunities. 1,401 DS3s and 42 Sonet Rings impacted. We have 3+ fiber techs at the cut site. It has not been confirmed if this is impacting multiple carriers." He followed up at 1717 Central to add, "20 of the 40 have been restored. I was told the other 20 should be restored within an hour. I am trying to confirm the ETR and to ensure it includes all the ds3s."
