Cable failure isn't random. It's a function of age, metal fatigue, and what the weather does to exposed hardware, and this area has all three working against it. With median housing dating to 1984 and plenty of stock going back to 1938, a large share of doors in this service area are running cable and drum assemblies well past the stretch where fatigue cracking starts at the swage fittings - the small pressed sleeves where the cable loops around the drum.
The climate here is the other half of it. Winters are cold enough and severe enough that an unheated garage swings through repeated freeze-thaw cycles every season. Moisture gets into the cable strands, rusts from the inside out, and you don't see it until a strand snaps under tension - usually on the coldest morning of the year, when the steel is least forgiving and the door is heaviest to lift by hand.
Newer doors with factory nylon-coated cable hold up better against that cycle, but a lot of the 80s and 90s stock in this area never got upgraded. The hardware still works, right up until the morning it doesn't.
