Everyone is missing the fact that this is just the last mile speed. I would guess that the uplink is very heavily oversubscribed. Indeed, from TFA, his ISP is a boutique kind of ISP (at least in USA they are nearly nonexistent unless you are rural -- I happen to be and have similar access to my ISP) and he even had access to the POP. The edge switches only have a 4x40/100G uplink in this case. The connections can obviously be bonded but the ISP remarks on their own page that the uplink is "just" 100G, ie not utilizing the full capacity available to the hardware. This is great for sporadic (very high peak to average consumption), residential type of use. Sharing such a high speed link across many subscribers is great. But in no way is this capable of running high bandwidth streaming servers, datacenter-like, from your home, as some are suggesting. Just 4 customers like that would consume the entire bandwidth. No sane ISP would allow even 1 customer to use all their 25G, continuously, that they might argue they paid for. The peering/transit that the ISP has is also a hugely important factor to how "good" this 25G connection really is. I'm not knocking it -- I wish I could get even 100M. But at the end of the day, a 1G connection that many USA city dwellers can get will be just as useful as the provisioning of such will be vastly different than the provisioning of this 25G service.
