What is 'redundancy' in tech?

Redundancy in tech means having backup systems ready to take over if something fails, like Microsoft’s servers unexpectedly going offline. It's about duplicating critical components to prevent a single point of failure. This ensures services like Teams and Outlook remain available, even if one part of the system breaks down.
