Premise: and they made a dramatic effort of trying to reduce down time down to nothing and today uh i can't say that i can remember the last time it went down uh several months it's it's just up all the time now they take it down like on Sunday nights like for a couple of hours to do maintenance or whatever but uh unless there's something dramatic that happens with the telephone system uh usually doesn't break down and i think what they're doing is they're using satellite somehow

Hypothesis: They don't take it down unless they have to for maintenance.
Relation: entailment
