> I don't understand what idiot designed an airport without backup connections.

I have literally spraypainted the pavement and wall - "One fibre goes here, and down on the corner there, the other fibre goes there" - just to ensure a good separation of routes. I want the pinch point to be within the rack that the routers sit in.

I don't get why an airport can't do similar.

That airport did have two redundant connections, this was a swiss cheese failure where one was under maintenance and the other was severed by an independent event.

So they didnt have a redundant connection. They had 1 live one that was severed.

they did... it was just singly redundant. they would need double redundancy here. so 3 connections, not 2

Taking one connection out for maintenance and leaving only 1 live connection is not redundancy, it is a failed backup.

Redundancy is always having more than one live connection.
