They aren't talking about general purposed datacenters, but satellite uplink stations. These new constellations of low-Earth orbit (LEO) internet satellites (like Starlink) can network with each other but eventually need to downlink into a big terrestrial dish where the traffic meets a fiber backbone. It's position in the southern hemisphere, middle of the Atlantic and political stability (still part of keeping the sun from setting on the British Empire) would make this an interesting place for downlink stations.
Not a ton of jobs, but some CapEx for construction and probably a couple dozen people year-round.
