MB, There is usually a main trunk line that goes for hundreds of miles and individual strands come off the main line to customers just like a tree and its branches. The extent of the outage just depends where along the path the trunk was cut. Closer to the root, more customers affected. As long as these fiber runs are it would not be hard to find a spot to cut and cause a major outage. One of the problems with fiber is that it is so fast and has a much higher carrying capacity than copper wire thus more customers or devices are on a single cable. If a cable gets cut the larger the group affected. It really surprised me that they were so open about how vulnerable the system is. I know it needs to be addressed but why put a big flashing sign that says cut this cable and we can’t do anything until its fixed. Nothing like showing the enemy the playbook.
