at this point the _last_ thing i care about is my email.
where am i? am i ok? how are my friends/loved ones?
once those are in place, it becomes clearer how to get back to "normal"
On systems that receive regular updates, SSH can fail for many reasons other than authentication problems, after all.
Is it fast? No, but that's a feature.
But it does mean I get to lean on the existing processes and identity verification already part of the government bureaucracy and the courts as my backdoor.
And this is assuming the server is somewhere else on the cloud.
Or I have proper backups synced across the world on different providers. The likelihood of everything failing is not a vector I worry about. If that happens I have bigger problems to worry about.

Who can presumably get you in touch with the relevant embassy or consulate or, failing that, local authorities.
