Interesting. If I had experienced this, I'd probably pick a random cloud provider, recreate the entire service in their cloud, image and document it, and have that documentation ready if I ever experienced another fire drill like the one yesterday.

Far easier to spin up a few large VMs on AWS for a few hours while you fix an issue than provision identical backup dedicated servers in a colo somewhere. And you can potentially just throw money at the issue while you fix the core service.

¯\_(ツ)_/¯
