I've worked as a faults analyst in several ISP's for 8 years. I am sure someone on this site could provide actual figures - but the main thing to understand is that all ISP's will have spent a lot of money on protecting their core / backhaul network's and will have alternate routes etc in place for when things do go wrong, and most of the kit will be in large, safely locked hubsites where very few people have access.

The cable in the street from your house to the exchange / hubsite etc isn't - it degrades, gets damaged by people building things, weather affects it, and sometimes gets simply vandalised and is by far the most vulnerable part of your internet connection.

You personal experience does not really give a good overall view of what to expect when you are trying to design resilient service for someone else.
