Last Friday, our central IT infrastructure, mostly running on Microsoft Windows, got infected by some ransomware. All central systems got shutdown and a process started to reset them to the last (presumably) safe backup. Three days have passed since then and systems providing mail service (the communication service I rely on) are still not operational. It is amazing that it takes several days to restore regular service after such an attack.
I assume that email to me will be bouncing already and automated systems may decide to block my email address beause of such bounces. A fun week ahead.
