Starlink

The goal was to reach altitude with new booster rockets. That was a success.

The landing however, resulted in a catastrophic explosion.

If the flight vehicle is destroyed in a flight test, well, IMHO, it is not a successful flight test.

Look at the flight video. How many colors of exhaust did you see? Read what Elon Musk said about why they could not make the required thrust for a softer landing. It was a very successful test in that Elon Musk got the data that they was looking for. He had stated there was about 33.3% chance of no failure. It took off and made the stimulated reentry and made it back to the landing point and more or less cleared the remains of a one off prototype very quickly.

That was a beta test on steroids. Good thing nobody signed up for the ride.

The fiber however goes back to a central location which has a switch and a uplink to the next hop.
If you have 30 houses each with a 100mbps connection which all go to a office that has a 2000mbps connection to the next hop and all of those houses are maxing out their connection, when the remaining 10 jump on, or they will all be rate limited to 66mb by the next hop.
Yes, you will be able to verify 100mb to the office, but the internet speed will only be 66mb if everyone is maxing out their connections at the same time.

That's not really when the problem comes in to play. If the system is designed properly, it will handle that load with little effect apparent to the users. The problems comes in when the ISP adds another 20 or 30 (or more) households to that node without increasing the backhaul capacity. Now you have 50 or 60 households sharing bandwidth on a node designed for 30. In normal times with all 60 on running emails or forums like this, it's likely no one would notice. But evenings when they all want to watch the vidiot tube and stream music and 'zoom' with Granny .... well ....

I see that way out here in the low population boonies. Daytime or early morning, I'll get 26M or 27M on my 25M DSL connection. Peak times in late afternoon, early evening, I usually clock 23 or 24.

Must not be too far out with speeds like that.

Some times a design has to take into account the amount of money that is going to be invested in the system. So the design may work properly, and not be able to supply full capacity to all of the downlinked devices.

It's called Bandwidth Exhaust and happens quite frequently on DSL Systems, fiber, rarely.

Probably on a fiber fed Node then copper to the house

Yup. Fiber about 5 miles from the CO, then copper 6,000', two bonded pairs of decades old 19AWG.

Methinks some peeps are in for a big disappointment...more bandwidth is not always the solution to latency and slow network issues...!

You just need the total capacity these days. Network and server appliances are smart now...they will give you what you need up to what you pay for Just like today's cloud....

Starlink can link everyone anywhere to the internet, doesnt have to be perfect but it must be useable I lknow there are experiments on going with balloons that also provide free internet hotspots but only when in range-aka google balloon, aka Loon.
