alt Hacker News> When it went to flip into the backup, we discovered that the backup fiber had a break
Pretty grim that a life critical system wasn't designed to report that the backup fibre was unserviceable until they attempted to switch over to it.
I wonder how long it was down? Days, weeks, months?

Sometimes your multiple fiber paths end up in the same bundle, severed by the same backhoe. It's always a fun day when that becomes apparent.
That's very uncharacteristic, especially given all those contingency requirements (backup policies, failovers, testing schedules etc.) imposed on corporations/companies in the wake of 9/11.
Besides what the others have said, speaking from a neteng perspective, sometimes backup lines (and the core infrastructure in general) are engineered in such a way that it can't easily be tested properly without taking other things down, or manually rolling a truck specifically to test it in isolation with extra equipment.
Not saying that's what is going on here, just that it's possible.
A lot of people don't check their backups until they need to restore.
A lot of people are incompetent.
All these cable/internet service companies are incompetent as it gets.
I am paying, $1000, $1800 & $1900 for the same service at 3 different location (20 mins from each other).
Two locations, I also have old coax lines that are still active, but not paying for it.
When I bought two businesses, I learned that they were paying for a dedicated fiber but using coax service.
At one of the location, we had fiber, and paying for backup coax and wireless. But if you turn off fiber box, it wont fail over to either one.
I wouldn't surprise it was down for weeks and no one bothered about it.
