Set up a second internet line for resilience

A backup connection, such as a second fibre line or a 4G/5G failover router, automatically kicks in if your main line drops, which matters most for businesses that can't afford downtime — card payments, VoIP phones, cloud-only file access. Many modern firewalls handle the failover switch automatically within seconds.

Coach's tip: test the failover at least once — plenty of businesses discover their backup line doesn't actually work only when they need it most.
