I don't think they are ever going to run gigabit over to me if they haven't by this point.

It's not that expensive everywhere. In the UK I can get 1000/1000Mbps for £29 a month, and 8000/8000Mbps for £99 a month.

with 30% inflation in the euro area over the past 10 years... the price has maybe gone down in real terms by staying the same?

It highly depends on where you live.

I can get gigabit for about €32,50 a month. 2gbps for about €40. Unfortunately, the cheap ISP that offers these rates doesn't have IPv6 so I'll stay with my current one. €70/mo would get me 4gbps symmetrical with another ISP. All of those include a WiFi 7 capable router, of course.

Prices have increased, but high prices are a local problem. The €35 price for cheap gigabit would equate to about €20 in 2000, so I think prices have stagnated alright, but speeds have evolved a lot since then.

70 euro a month for gigabit? That's a great price! And way, way, way, more than you need for self hosting a website (maybe more for other things?). I've hosted my .com website from home since the late 90s and anything faster than a couple megabits is just fine .My current 80/10 megabits connection from comcast is $115/mo and has a 1.2TB data transfer cap with $10 per 50GB over. Even with such a terrible, expensive, exploitive ISP I host my dot com from home just fine.

Trying to host from wireless would probably not work so well. Do they even give you a real ipv4? And even if so, you're round trip time is inherently randomized which leads to tcp backoff and slowdowns in this context.

Verizon FiOS has had symmetric gigabit service available for well over a decade for a reasonable price.

Where in the USA are you?

Except for fiber, for all providers I'm aware.

My home fiber is symmetric gigabit in Seattle, for $65/mo
