Apparently copper service is eroding and little effort is made to bolster it.
This building is 15yo, its alarms (fire, fallen-and-can't-get-up) and wifi are AT&T copper. The box is 30 feet off the NW corner. An AT&T truck is out there almost every day switching pairs trying to find ones that work. We had to hire security guards to monitor the interior while the services couldn't be restored for 2 weeks.
Even the AT&T cell towers in this region (decaying metro, little Detroit) are losing functionality. The same phone on the other side of the county worked 'fine' on the couple bars I could get down in a valley. Here, while I have all the bars lit up, it drops words, sentences, paragraphs, entire calls on an ongoing basis.
Several conclusions come to mind. One, that fundamental infrastructure we once took for granted has deteriorated like the Minneapolis I-35 bridge (the starkest example), the NYC water system that barely delivers more than it leaks, prolonged electric outages from weather or just 'system events'. Two, as might be anticipated, money chases money. I'll bet AT&T has no problem at all serving Cowboy Stadium across the county with cell and wifi. But why should they give a shatner what happens in a neighborhood that even Mcdonalds has abandoned? Three--or 2.5--that expanding emerging services takes absolute precedence over integrity of established services.
This is what happens when you let MBAs run everything. Trust me, I saw during the downfall of Dell and I've seen it everywhere since. They're only in it for the money. If your junk don't work, that's your problem for being on the wrong end of the curve. We'll still sell it to you with TV commercials. But you know that mishmash of microtext at the end you can't read? In there the lawyers have inserted boilerplate that invalidates everything the announcer promised you. You HAVE noticed that, haven't you?
