I smell marketing hype.
Don't get me wrong, I'm super jealous and of course I'd love to have a 25Gbit connection at home.
But I think we need to step back from the Kool Aid for a moment and ask ourselves:
- What's the likelihood of the remote servers you are connecting to having a 25Gbit connection ?
- Even if the servers do have >=25Gb connection, what are the chances of the server sysadmin allowing one user to hog a large chunk of capacity ?
- Even *IF* the answer to the above two questions is positive, what are the chances of your magical 25Gbit ISP having sufficient backbone + peering + transit capacity to fulfill the 25Gbit to its users at all times ?
I foresee a lot of contention/bottlenecking and basically a lot of reliance on "not everyone will be using it at the same time".
I also suspect the small-print of the ISP could make for interesting reading.
EDIT TO ADD:
Found the relevant clause in their conditions:
The Internet subscriptions for private customers are intended for normal personal use. Init7 reserves the right to temporarily or permanently restrict or discontinue the provision of services for connections whose data volume exceeds 0.5 petabyte (500 terabytes) in a period of 4 weeks, or to take another suitable measure.
I'll leave it as an exercise to the reader as to how long it takes to transfer 500TB on 25Gbit ;-)
