Let’s face it, you cannot be monitoring your website 24-7 but still for webmasters who are generating revenue from their websites, you need to be there as soon as possible to fix things up when there’s a downtime, or else you’ll potentially suffer a revenue lost.

You could lose visitors, or worst, loyal followers.
