I like the lessons and the story as reported by the BBC and other outlets (see below). Not the part about a ransomware infection bringing a local government agency's email to its knees, but rather how they adapted, didn't give in, or give up. They dusted off old manual analog tools, including typewriters, to maintain basic operations while the digital environment was restored.
The lesson is to have a plan for situations when the power goes out, the phones go dead, or when digital systems become unavailable. Will employees be paralyzed in a fugue state or will they be able to adapt? Basic communications and manual tools are typically needed to sidestep total productivity loss.
Where is your Disaster Recovery and Business Continuity (DRBC) plan and how confident are you it will be applicable in the face of digital service loss?
