Many years ago, my internet provider
was Comcast. I can't remember how long I'd had them before I started
having issues, but it was at least a couple years and probably closer
to five. Actually, now that I think about it, it had to have been a
decent amount of time. I distinctly remember customer support's
favorite fix-all for any issue I had was for me to buy a new modem.
They kept saying that mine was “out-dated.” No, my modem wasn't
the newest model, but it was perfectly fine. It certainly wasn't
going to hinder my speed as I was only using their slowest/cheapest
plan.
Honestly, service was pretty decent for
most of my time with them. I don't recall experiencing anything out
of the ordinary until my final year as a customer of theirs. That
year, the quality didn't decline; it fell off a cliff. Two words:
intermittent interruptions. Without warning, as service failures
often go, internet access was gone... and then it was back.
Sometimes the little lights on the modem would reflect the service
interruption; sometimes it looked perfectly normal. Sometimes it'd
last an hour; sometimes it'd last all night. Inconsistency was the
hallmark of the failures, and it was the noose around the neck of the
technician.
