I'm afraid it all just seems to play to my pet theory on such things.
Companies are happy as long as they 'tick boxes' and it's not 'their' fault.
I'm sure the fibre company never instructed anyone to cut corners to get the job done, I daresay they have stats that prove their flawless records on safety. I daresay the contractors company didn't tell them to cut corners either, well not directly, but by dangling a fiscal carrot (possibly paid by the meter they pull in, or the number of jobs a day they complete) that company gets results in terms of productivity, and keeps it's contract, and nothing is said until something goes horribly wrong .........
Three faults I attended last week were directly attributable to poor contractor workmanship, though not as obvious a bad outcome as the pictured infraction, they still cost time, money and customer grief.
For example .... I attend an FTTC fault, the customer has never had service since the go live date ....... After a bit of fannying about I discover that the line, on record as going through PCP A and having allocated FTTC ties in there, is actually
routed through PCP B which has no fibre twin ...... And yet someone had still stored a test on and connected through the DSLAM ties in A to dead pairs ......... They got paid for doing that .... On paper they looked great, a textbook job completed quickly and all the quality gates passed. Quality.
On another, same scenario, this time they've sent the FTTC sync down the E side back to the exchange rather than on the D side to the customer ....... Again no excuse, a nice easy cab to work in, easy to 'read' clearly marked up as per recorded routing.
I shan't go on .... it's soul destroying.
These are the actions of people whose only motivation is to make as much money as quick as possible (I hasten to add I checked, these weren't my companies staff, they were contractors) And in the end the only people who suffer (part from my hurt pride) are the punters.
These ethics cause people to cut corners, in the OP the outcome might have been MUCH worse.
