I don't know how long ago the library of Alexandria was burned down. But what I do know is that we never learn the lesson. It's rather stupid to store public research data (i.e, excluding classified info) at a single location. There are any number of unpredictable future scenarios that can lead to this same unfortunate outcome.

Scientists and politicians should work together and agree to store and host such research data in multiple countries, including with rival nations. That should make it a lot more resilient against such eventualities. It won't cause any security risk. After all, you were going to publish it anyway. Why waste the information worth a lot of money and effort?

But instead of that, many governments and greedy corporations go after independent groups who do exactly that - scihub and internet archive, for example. We as a species possess the stupidity of stubbornly avoiding the obvious right path.
