Fiber is less expensive than and more than 10x faster than starlink, in fairness.
Our 5g towers seem to run off the fiber lines, so it’s not really a backup (and gets overwhelmed anyway).
I’m considering getting fiber in addition to starlink, but I wish they’d just buried the lines.
I see telephone trucks repairing downed lines we’d rely on many dozens of times a year. Digging a trench would probably pay for itself in a year or two.
