Price business pipes where they won’t cut you off for saturating that 24/7.

[edit] and that have good deliverability worldwide, no weird paths to other consumer IPs that intermittently fail to route or inexplicably have dial-up transfer speeds. And have anything like a real SLA.

I don't think they legally can in number of European jurisdictions. This isn't like Comcast overselling their copper cables - brand new fiber paid for by the EU comes with certain obligations.

Try uploading at that rate for a few months non-stop and see how long your residential ISP will continue doing business with you.

That can be taken out by a particularly unfortunate shovel or truck though, and isn’t sufficient to run a business on.

For 800k I would have 20000 different connections. This would allow me to survive many unfortunate shovels per month.
