These kinds of speeds are available in Switzerland because their laws state that any fiber laid down must be usable by competitors, so that ISPs must compete on service alone. I wish we had that in other countries as well.

But then who pays for laying down the fiber? What company would want to pay that cost when others can use it?

The company pays but then it can also use other companies' fiber, so sometimes it's worth it to do so in order to show that they have coverage in a certain area where there might not be fiber (that they then lay down), and also that they cover everywhere else.

It's quite a clever system that uses market greed to incentivize building. It's the same system as railroads, imagine if railroads could not share tracks with each other.

Grants from the government.

Some places also vote to have the city or town connect with Fiber which then puts tax money aside for it.

In many places it is the power companies that run fiber and they are mostly partially or fully state owned. The lagest ISP also has the state as the majority share holder.

I'm a proud owner of a 1 Gbit/s fiber connection with a 100 Mbit (wired) network in my house. I want to upgrade it to match, but I don't want to go through the effort because I never run into download times for anything.

I've got AT&T Fiber's 5 gigabit symmetric service (with a Ubiquiti equipment stack that handles 40 gigabit without issue) and while its been very stable and I win all nerd fights with my speed tests, I've been thinking about dropping back down to 1 gigabit because I don't find much value out of 5. If it was cheaper ($180/mo for 5 gigabit) maybe I'd keep it but Astound/WaveG is offering gigabit symmetric for $50/mo wi…

What Ubiquiti equipment are you using? Doesn’t their router top out at 3.5Gbps?

UDM Pro

USW-Pro-Aggregation

USW-Pro-48-PoE

US-XG-6PoE

Recently bypassed AT&T's residential gateway by getting a XGS-PON on a SFP+ stick, let me shave off 2ms and gain a couple hundred mbps each way, in addition to removing their crappy gateway.

For home runs I'd recommend using duplex instead of simplex (the cable out to the provider has to stay to whatever they require of course). For a 100M cable it's $37.47 for the duplex and $24.48 for the simplex, the price difference of $13 for a really long run. The price difference of 2x 25BASE-LR (duplex) vs 2x 25BASE-BX (simplex) transceivers will be more like $60. Even if you want to stick with simplex optics eve…

The price of 25GbaseT (rj45) is still very high. 10GbaseT (rj45) is coming down very nicely though and some motherboards, routers and high end access points have 10g ports onboard. I think it's actually cheaper to go 40gbps QSFP and run MPO cables (4 pairs internally) than it is to go 25g fiber. This is pretty much the case in datacenter right now for anything that doesn't need to go over 300M.

It's not. 25G and 40G transceivers cost the same and MPO cables are more expensive.

We had it in the US but the Courts overruled Congress & demanded the FCC carve out an exception of the required Unbundled Local Element/Local Loop Unbundling requirements of the Telecommunications Act of 1996. By 2001 it was clear we weren't getting unbundled network elements after all. https://docs.fcc.gov/public/attachments/FCC-03-36A1.pdf

It was & is one of the most stunning activist court decisions to have hit the US ever. Big companies sued, saying fiber was expensive & that they should have sole control over next gen telecommunications technology & the courts ignored the legislative act & handed incumbent powers total control. Revilesome; one of the biggest constraints in US infrastructure in general.

The FCC has been busy 5hese past couple years unwinding remaining requirements for dark fiber & other remaining protections. I somewhat care but the obliteration of last mile protections that enabled competitive carriers to exist at all makes the overall market so unavailable & locked up that it's less relevant.

How many hours can you saturate that 25 Gbit connection up and down before support calls you and tells you to knock it off?

In my case, init7 defines that "fair use" is 0.5 PB per month. So that is about 40 hours until they start asking questions, I guess :)

I doubt I will be any close to that.

Earlier quoted context omitted.

As long as you have a static IP address, this is trivial and typically very reliable. Throw an ATS battery into the mix and the internet will be super reliant, even when the power goes down. Am doing this at home with a fibre line and it's been super reliable.

Dynamic dns is a thing?

My ISP uses dynamic dns, but it never changes unless my modem is down for several minutes. My router has a script that updates a dns entry if it changes, but realistically this rarely happens.

The choice for my fibre ISP is between static IPv4 or carrier-grade NAT. Both options get IPv6.

I ran about 8TB on my fiber in one month, and no ISP notices to speak of. That's only ~25mbps sustained. You could easily push 500+TB on a 25gbps connection if you were doing something naughty with it, and I'm sure you'd hear from them about it if you did!

I regularly use 5 - 10 TB on my fiber each month, and have never been contacted.
