I've seen troubles with T-1 loops in wet weather due to moisture getting into poor splices or repeaters. Actually any physical fault in the cable - could be squirrels chewing the insulation or (in rural areas) hunters with poor aim. Many years ago I worked for Ma Bell in Brooklyn, NY. This was before fiber optic. T-1 links were all copper with repeaters about every 1/3 mile. (Others can be more specific as to seperation between repeaters.) Repeaters were in housings in manholes. After any maintenance the housing was supposed to be pressurized with compressed air. Anyway, either due to poor seals or workers with an attitude - every time it rained T-1s would start to fail as the manhole(s) filled with water. In time we knew the order of failure - depending on the repeaters location in the housing. Bottom first, etc.
