Yes the probe here is a lack of monitoring.
You can get two separate failures in short succession, where the first one hasn’t been fixed. For critical devices that’s why you have tertiary backups, ideally on different technology compel you. For one major event I had diverse fibre and satelite and microwave. Lost microwave and satelite to electronic warfare but the fibres were ok. Ofcom were really pissed about it, but nothing they could do.

No?
Like, okay, monitoring reports what there is no link.
Now what? Somebody gets a hi vis vest, a hard hat and goes along the cable to investigate the reason?
There is nothing monitoring could help, especially if the cable was cut recent enough.

> An RFTS enables fiber to be automatically tested from a central location. A central computer is used to control the operation of OTDR-like test components located at key points in the fiber network. The test components scan the fiber to locate problems. If a problem is found, its location is noted and the appropriate personnel are notified to begin the repair process.
