I've long wondered what the real-world impact would be of a Carrington Event [0] in the 21st century. If we're underprepared for "black swan" pandemic events, I suspect we're even more so for solar flare / solar storm events, given that unlike the long history of pandemics, we have no historical precedent for severe solar storms since the dawn of electronic technology. I'm almost entirely ignorant on this subject; but my fuzzy understanding is that the only data formats which are guaranteed to survive such an event are optical media, and "paper backups" such as this one. I'm very happy that the GitHub Arctic Code Vault now exists; for closed-source OS/infrastructural code, I'm curious if any major vendors have their own equivalents.
