Yes, it can. Trenchless pipelining is a versatile system for repairing damaged sewer lines that works for most situations.
A repaired pipe will be lined with a PVC lining that lasts as long as any brand new pipe.
The hundreds of submarine cables on the ocean floor essentially are the internet.
The typical lifespan of sewer line materials used in the last century or so is about 30-50 years. That means that if the pipes in your yard haven’t been repaired or replaced in the last 20 years or so, they could be due for failure.
All data is just encoded energy, and light is the fastest moving form of energy in the universe. Fiber optics are tiny strands of glass meant to take advantage of this speed by conducting light between two points.
Many materials have been used for underground sewer lines in the USA over the last century or so. The inevitable result is that pipes fail, eventually.
Sewer lines eventually fail, due to aging, erosion, the shifting of the earth, or penetration by a root.
Because parking lots, driveways and structures are less permeable than natural surfaces, property development leads to run off problems: excess water in certain areas causes flooding and increased flow rate, which in turn leads to increased erosion.
When your sewer lines backs up, the problems pile up, too. You’ve got no usable bathroom until the issue is resolved.
The short answer is no. At least, that’s not the alleged plan, and it seems unlikely in the near future.
The intent behind Starlink is to meet a demand that the internet service providers (ISPs) are struggling to meet: rural populations. Low population density means that there are fewer customers to service. Fewer monthly subscribers means less income to make up the costs of installation. Naturally, the providers are going to go where the money is first. And if there’s not enough money in rural areas, broadband may never come there at all.
