Svalbard is not a country, but a remote archipelago of Norway.
The main island, Spitsbergen has a population of 2.5k people, they don't allvuse the Internet (certainly not all at the same time), and they do not pay for gigabit home internet, more like 75Mbps.
For reference, the Southern Cross fiber network connecting Australia to the U.S. does more like 10+ Tbps.
All of this but also even in the case of bigger lines, a lot of home Internet traffic is not routed globally if you can avoid it. CDNs cache content on the same physical continent as much as possible, things like Netflix are usually streamed from your local ISP. A lot of traffic over the Internet is extremely unexciting things like Windows updates as well, which are generally globally served by a CDN (or even peer to peer sharing from other Internet users nearby).
