I can think of two things. Large time series data for large areas with a lot of attributes like temperature or other atmospheric data or a huge amount of point clouds or comparable 3D Data.

SAR and multispectral imagery. It’s not difficult to work with when you’re only dealing a small and well defined regions, but the bandwidth and storage requirement definitely increase once you start doing daily global composites. We’ve actually moved everything into a data center with a 1gb connection. The trade of being that we have several orders of magnitude more storage and computing capacity.

It’s crazy because among friends I’m the only one working with geodata (remote sensing, too) and the last few days I keep stumbling upon people who already do some work in the same area and are probably much more advanced than I am. Good luck with your endeavour!

>I'd now refer to my country as a country in the global south Meaning what, in the southern hemisphere and not Australia or new Zealand?

It isn't a geographical denomination, but rather socioeconomic and political. Most of the countries in the global south denomination are actually in the northern hemisphere.

That seems like bad jargon.

Not convinced by the use case section. Very few servers will allow you a full 25gbit download, let alone anything more than a 1gbit (and often less). And if you own the server on the other end, that sort of bandwidth comes at a cost. I think beyond 1gbit, the benefit become super marginal and the hardware expensive.

> I think beyond 1gbit, the benefit become super marginal and the hardware expensive Is it expensive though? We spend how much of our lives online. How much do you think this all-spanning life upgrade costs? What is the price of never ever dealing with buffer-bloat? Take a guess. I calculate it as a one time $356 cost plus labor. You might have paid more for your wifi system. 128 port 25gbe switches are around $20k (…

The calculation works only if each customer has their own fiber.

Unfortunately for most (consumer) FTTH deployments, that's not the case. Most of them are GPON, where the initial deployment was more effective, as up to 64 of your customers share single fiber, but then that means all of them have to upgrade all 64 of them at the same time, you cannot do them one at the time (see also the speed of XG-PON upgrades).

Additionally, many providers forced use of their CPEs. If you can send out SFP module and the customers can put it into whatever they want, it is much simpler, as replacing CPEs for all the customers on that fiber.

No %#*^ing way is he saturating a 25gbit connection to download a PS5 game — not on Sony’s EMEA servers anyway. He’d download the largest PS5 game out there (Borderlands at 50GB) in a minute anyway — probably before he could reach the full 25gbit. On a gigabit connection, he could download Borderlands in under 7 minutes. If that’s too long too wait, then having a faster connection isn’t this guy’s problem. The only u…

Why should he have to wait several minutes?

25GB/s is overkill, and 640K ought to be enough for anyone. Those quotes age well.

1 Gbit/s is pretty close to still being overkill. 25 Gbit/s is laughable overkill and appears very likely to remain that way for the coming decade. Consumers around the globe have had increasingly common access to 1 Gbit/s for a decade and there still aren't any other great, common use cases for it beyond very high quality video streaming. It didn't take very long for computer use to need more than 640K by comparison…

1 Gbps is slow. Even recent wifi can plausibly exceed 1 gpbs to a client. Pretty much any modern HDD (let alone ssd) can read or write faster. USB 3.1 is an order of magnitude faster and display port 2.0 tops out at about an order of magnitude faster than that. It doesn't really make sense to leave the main physical network interface so far in the dust, let alone claim it's overkill.

“ The init7 engineer met me in front of the building and explained “Hey! You wrote my window manager!”” That’s so cool. Very cool he got to participate in the upgrade process. I had 1G up/down through FIOS (Verizon FTTH) but eventually downgraded to 500M because I was saving perhaps 10s a day for 50 bucks a month. There has to be a server at the other end willing to give you data that fast.

We were honored to have him and he was actually of real help ;)

25Gb/s is just overkill for residential use. It's really cool that's it's available, but I fail to see a use case over my 500Mb/s home connection. Even for the servers that I manage and that are bandwidth-heavy, 10Gb/s is way overprovisioned for now. WiFi goes up to 1Gb/s, if you're lucky. Sure, some WiFi-6 APs have a 2.5Gb/s connector, but that's not what you want or need, unless you're a high-density enterprise. Wi…

Wired, you can do 10Gb/s for server systems, which are, amongst other things very loud and not very suitable for placement anywhere near humans.

My 10gbaset switch is all of 23 dB when the fan kicks on and I have other switches with sfp+ that don't even have a fan.

I wonder what systems the ISP has in place to avoid such networks becoming sthe source of DDoS attacks. Given the generally dire security of home routers (and understandably low security of most home networks/users) it feels a little like giving people far more power than most can safely wield.

It's a niche/small ISP, which mostly targets advanced users.

Though for regular users, they can get 10Gb/s for half the price of init7 with other isps (but probably worse peering as mentioned in the post).

As a German I weep and cry. 25Gbit/s seems so so far off. And I live in a major city. I only get 150Mbit VDSL at the moment. I have no cable connection so one of these to get the theoretical 1Gbit/s download is out of the question.

The maximum speed available at my London address is 35 mbps download and 5.5 mbps upload. It hasn't changed in the seven years I've been living here. The best mobile connection I get is two bars of 3G unless it rains.

Oh boy I feel for you. Is it because of the house/street or a general issue in London?
