When I was working with Svalbard, Internet connectivity was through a

It has, as Steinar says.

For those interested in the necessary elevation at 78 degrees north, I
found a nice picture of the antennas here:

There aren't any mountains in front of the the antennas. However there
is a mountain between Isfjord Radio and Longyearbyen (the main
settlement), requiring a relay station on the radio link between these.


The NyAlesund SGO

is some distance North of Longyearbyen (how many places can say that ?), and I used to have a nice picture, which alas I cannot find, of the satellite link (not the 20 meter dish in the picture) apparently pointing at the mountains.

It does indeed have fiber now, and has been used for eVLBI
