I'm not sure if there is a firm grasp on the geography of these states.
Virginia and NC are medium sized states, that yes, touch the ocean where a large Cat 5 hurricane might launch itself upon their beaches. It's never ever happened before, but hey it might.
Now, I'm willing to bet that these large data centers are NOT on the beaches of these states, but perhaps just a wee bit farther inland. Perhaps even as far as the mountainous areas that run through the western portion of these. I don't know. I didn't look these things up, but if so a hurricane would die a fairly quick death as it moved inland in either area.
Now this does not include the possibility of a hurricane coming up the Chesapeake bay and into Baltimore or Washington DC. However if that happened, and DC was flattened on the way to hitting the Amazon data center in Northern Virginia, I think we'd have a few other problems than lost data.
