Slightly OT: Suppose you want to deliver a couple of 100’s Mbps to people in EU on the cheap, how would you do it? Assume it’s static files, so the server doesn’t need to be that beefy.
Hetzner would probably be my first choice. Even though I’ve hade some strangely slow connections there sometimes.
Other more enterprisey providers like Datapacket seem to be significantly more expensive.
I rent a VPS with Leaseweb. Their prices aren't the lowest, but their performance is better than many cheaper alternatives.
There is no unlimited data. Either data centers are lying to you, or they're going to end your contract the month after you start sending hundreds of TB.
Their data plans clearly state the traffic limits and their terms state the overcharge you can expect. If you need more network traffic than the 15TB they offer VPS servers, you can probably just ask, set up some dedicated , or set up a CDN (listing price: "contact us", though Cloudflare is likely cheaper) or rent yourself a full colo rack.
Other VPS providers are similar, but always check the uplink speed (I've noticed German and French providers tend to stick to only 100mbps) and the data limits; anything that sounds like "unlimited" isn't and should be avoided if you're worried about data cost. Your only real option is to avoid the cheap market and go midrange or high end because data is expensive, especially at over 800mbps consistently.
I mean FDC offers 1Gbs unmetered[1] (and I do think they actually mean unmetered), dedicated for $199 / month . While being ≈ 4 times more expensive than a cheap Hetzner dedicated box mentioned in OP, I don't think OP would have gotten an email from them.
I was thinking that maybe some provider basically was reselling ≈FDC dedicated boxes with VPS's that tailored to high bandwidth usage. Of course being more expensive than run of the mill VPS's. But maybe the server performance per price, and bandwidth price equation doesn't make it so attractive. Even if you're just pushing static files, you need some CPU to saturate it (especially considering tls termination)
