Yep. Having actually worked on this sort of stuff I can confirm.
Your ISP doesn't have enough bandwidth to the Internet (generally speaking) for all users to get their feed directly from a central location. And that central location doesn't have enough bandwidth to serve all users even if the ISP could. That said, the delay can be pretty small, e.g. the first user to hit the cache goes upstream, the others basically get the stream as it comes in to the cache. This doesn't make things worse, it makes them better.
I don't bet so I have no clue, but why is that? Are people able to place bets in the middle of the match or something? I would have assumed bets get locked in when the fight starts
This is kind of silly because the delay between actual event happening to showing up on OTA TV or cable TV to showing up on satellite TV can already be tens of seconds.
Or, hear me out here, it's a wild concept, just work.
You know, like every other broadcaster, streaming platform, and company that does live content has been able to do.
Acting like this is a novel, hard problem that needs to be solved and we need to "upsell" it in tiers because Netflix is incompetent and live broadcasting hasn't been around for 80+ years is so fucking stupid.
