Thank you for choosing Covad, now a MegaPath brand. I just checked on the nodemap and I don't see any outage that could've related to your Covad circuit in Los Angeles, CA.
I apologize for T1 Support not answering your call right away, but please understand that if there was an outage, that there is massive overflow.
I hope I can help you, Would you happen to have a circuit ID so I can assist you further?
