Build all above-surface structures out of inflatables. During heavy weather deflate and retract (5-10m). Use simple solid-state generators, e.g. https://en.wikipedia.org/wiki/Vaneless_ion_wind_generator

Are other structures safer against hurricanes?

An underground data center would work if hurricane safety is your top concern. In any case a location on land is probably cheaper to rebuild.

I think an eventual hurricane would not destroy the data center, only just the wind turbines.

What about earthquakes then?
