I kind of remember that they restored it by routing through Los Nettos. At home I was using the Cerfnet Caltech pop at the time, and had an outage for an hour or two (and lost power for about that long). The windstorm a few years later cut lots of above-ground fiber, though; lots more outages than any earthquake. I recall that CSUN was pretty well cut off (both net and roads) for a while.
I don't recall if the Hector Mine quake cut any fiber but there is a repeater building near the railroad just east of the fault-line crossing. There wasn't a ground break that far north so the cables probably weathered it OK but the building might not have. (amazing to have a 7.4 or so quake that almost didn't injure anyone; almost all the damage was from the derail of the southwest chief westbound.)
