Most technology is simply unreliable. Unless you pay a lot more for redundant systems. My internet provider here in NYC, Time Warner Cable, has had 3 outages in 3 weeks, two being a full day in my neighborhood. And that's on a $100/month 50 MB/s down and 5 MB/s up connection, the most expensive one they offer to the home. Unfortunately, like a lot of the US, Time Warner's infrastructure is horribly outdated, so these issues occur regularly. And, as with much of the US, we don't have any other options. Neither of the other cable providers service us. Verizon's FiOS rollout was abandoned. We can get DSL, but it's horribly slow (under 1MB/s up) and is notoriously reliable (when I tried it years back, it was down 8 days out of my 30 day trial period because a Verizon tech 'plugged something in wrong in our street's box'). So, I have to pay for a Verizon hotspot as a backup so I can 'reliably' work from home. Of course, the 1st of the 3 most recent outages Time Warner had, Verizon's LTE network went down at the same time.
So, yeah, that's the 'normal' of technology in the largest city in the United States.
