Be Proactive Not Reactive
Whether your business systems are in-house, offsite, or hosted in the cloud, this is an important reminder to have and periodically assess your business backup, recovery, redundancy, contingency, and continuity plans.
Generally, no system, regardless of the safety and redundancy protocols which may be in place, is completely foolproof against potential service disruptions or outages so it's essential to have appropriate plans in place to help mitigate against potential disruptions that may be crippling to your business.
Careful planning, assessment, ongoing training, and staying proactive can go a long way towards mitigation.
Be proactive, not reactive!
