Sprint spokeswoman Crystal Davis in Reston, Va., says one occurred at a construction site along railroad tracks between Chicago and Milwaukee, and the other was somewhere between Portland and Seattle.
If there had been only one disruption, the computer system would've been able to reroute the traffic. She says the failure Monday was caused by the combination of the two cuts. It also affected some other Sprint customers in parts of Washington, Oregon and California.
Davis hopes one fiber optic line will be fixed by 3 p.m. Pacific, which should put Alaska Airlines back in business.
