You know what is worse than waking up only to find you are two hours late for work? To wake up and find that your website was down the whole night. If you think that there is a way to get around that then you are right.
There are several tools for monitoring your website at all times of day, and this one is intended to work along with those. Named PagerDuty, it will let you be instantly notified when any situation arises regarding your servers. That is, PagerDuty sort of aggregates alerts (which can be collected using any monitoring tool of its own) and then calls you if a problem has been detected.
Notification methods range from e-mail and SMS to a phone call. Besides, the system works in a way that implies you must confirm the receipt of the alerts – until you do so, you will keep on being messaged.
A nice feature is that you can actually set a team schedule and determine who else will be contacted if anything went awry. In that sense, you can rest assured that your site will be up and running again before long.
