What the global IT outage taught small businesses

When a single faulty update took millions of Windows machines offline worldwide — grounding flights and freezing tills and offices — it was a stark reminder of how fragile "it just works" can be. You don't need to be a global airline to take useful lessons from it.

Lesson 1: updates need a safety net

The outage came from an update, not an attack. The lesson isn't "stop updating" — updates are essential for security — it's that critical systems need backups and a way to recover quickly when something goes wrong.

Lesson 2: know your recovery plan before you need it

• Do you have recent, tested backups of your important data?
• If your main computer died today, how long until you're working again?
• Who do you call, and how fast can they respond?
• Is anything critical dependent on a single machine or person?

Lesson 3: resilience beats luck

Businesses that recovered fastest weren't the ones that avoided the problem — they were the ones with backups, a plan and support on hand. Resilience is something you build in advance, cheaply, long before you need it.

You can't prevent every outage. You can decide, in advance, how long one is allowed to stop your business.
