At this time we are tracking an ATM backhaul problem affecting LATA9. This LATA covers DSL service for the Stockton/Modesto areas. We believe the problem to be on AT&T’s backhaul side, and are working with them currently to diagnose and repair.
Update: We have narrowed the issue down to a specific line card in an ATM device in our network. Due to the nature of the problem, we had to perform a reload of the entire device. This briefly affected customers in LATAs 1, 2, and 6 as well. We apologize for affecting previously unaffected customers while reloading this device.
