Every business, every service should give advanced notice for scheduled maintenance that would disrupt operations.

[Kera]

Scheduled system maintenance is part of all business organizations, be it offline or online. What is rude is not giving your customers an advanced notice on that.

Every business owner should give advanced notice of system maintenance to its customers.

Some service businesses always give this notice few hours to the scheduled maintenence and that always leave staff stranded.

This is standard business practice. You don't plan to disrupt services without letting the customers know and adjust accordingly.
