This internet speed thing is problematic, at least in part, because of perception. Let me explain.
First, just an observation, but fibre here in Europe is pretty ubiquitous.
Our home (where we live) is fitted with fibre, and we have a base rate of 600mb. I can upgrade to gigabit or even 2gb with the click of a button, but it's much more expensive, and frankly, I don't know what we'd do with that bandwidth.
Ok, so I'll get to the point: In many places around the world, you buy say, 100mb fibre, but actually get 10 or 20mb average. Sometimes you might get 100, but it varies, widely. I think many people are used to this.
Here in Spain, we have a law that forces internet providers to actually deliver the bandwidth that subscribers pay for, so if you have 100mb, you're likely to average that amount, 24x7x365. Often, with 100mb, you'll get 200mb at times, because that raises the averages from times when they're delivering less than what was subscribed. And I suspect guests might expect much lower speed than what is claimed. Because that's how it is in many places.
Most people are used to big numbers. 100mb, 500mb, gigabit. They really believe you have to have that bandwidth or else it will be slow. But in reality, 100mb is very, very fast.
Case in point: Our STR is a rural property where fiber just isn't available. We do have wimax, which delivers about 12mb consistently and reliably. With this bandwidth, we can run 4 separate Netflix UHD streams, simultaneously while many different smartphones or tablets are surfing the internet or even on zoom or WhatsApp calls. All without any noticeable glitches or slowdowns. This is the practical capability, not some arbitrary number.
The point is this: bandwidths are so high these days, that people have no understanding of just how fast they are, and have set unrealistic expectations of what they actually need. Or perhaps they're just accustomed to not getting anywhere near what they subscribe to. So, the faster the better. Gigabit will do, because I know I'll get 100mb or so. And I need that. Right?
In our STR, we deliver internet speeds verifiably suitable for everything they need, but I'm not inclined to tell them what the actual speed is, because they think they need a minimum of 100mb to survive. In practical use, it delivers more than enough, yet, many might avoid booking it on that misguided metric alone. So, I'm not inclined to run that test and broadcast it to the world.
And never, ever, has anyone ever complained or mentioned "slow internet". Ever. And we've had quite a few seriously internet consuming "digital nomads". Never a complaint.
But they've never been given an actual speed value. They might complain if they knew that actual number. But it has nothing to do with the practical use of it, which all seem to find perfectly acceptable.
