No, you don't. Oversubscription is a thing, a rather obvious thing when you go looking for it (evening Netflix time is horrible bandwidth on any ISP lately, including my Starlink connection), and you could comfortably handle hundreds (or low thousands) of customers at once on a single 40Gbit bird.
No, not everyone will be able to pull their max speed at the same time, but that's just not a use case you design an ISP for. Assume 20Mbit or so in the evenings for Netflix or Prime or whatever on most of your customers, then let the rest of the bandwidth shuffle around as needed.
- falcolas 5y agoOversubscription proved to be a problematic thing early in 2020, because of everyone working from home. This will ease up, but the old oversubscription numbers won’t work anymore as people have permanently changed some of their habits. And the bandwidth required by any given household will only really go up in the future.
