Yeah the requirements aren't too steep here. I could easily host this in my "homelab" if I gave a friend a key to access my utility room if I were away / unavailable.
But 2-3Gbps of bandwidth makes this pretty inaccessible unless you're just offloading the bulk of this on to CloudFront/CloudFlare at which point... it seems to me we don't really have more people running logs in a very meaningful sense, just somebody paying Amazon a _lot_ of money. If I'm doing my math right this is something like 960TB/mo which is like a $7.2m/yr CloudFront bill. Even some lesser-known CDN providers we're still talking like $60k/yr.
Seems to me the bandwidth requirement means this is only going to work if you already have some unmetered connections laying around.
If anyone wants to pay the build out costs to put an unmetered 10Gbps line out to my house I'll happily donate some massively overprovisioned hardware, redundant power, etc!
You can rent 10gbps service from various VPS providers if you can't get the bandwidth at home. Your home ISP will probably have something to say about a continuous 2gbps upstream anyway, whether it's through data caps or fair use policy.
Still, even in Germany, with its particularly lacking internet infrastructure for the wealth the country possesses, M-net is slowly rolling out 5gbps internet.
In Germany 2 – 3 Gbps outbound is a milestone, even for enterprises. As a individual I am privileged to have 250Mbs down/50Mbs up.
So it`s at least off by what any individual in this country could imagine.
