We actively monitor all of our hosting services constantly so we know immediately if a service fails. The system is monitored 24/7 by an external network to report on any problems. The engineers and programmers that developed your website are on site and on call 24 hours a day to guarantee you the reliability your business requires.
Most companies rely on you complaining when your website or part of it becomes unavailable, obviously a problem if your site goes down during the evening or early morning. In some case, it is not the whole website that fails, only a particular application. With a call centre you ring, get a fault number and hope that someone gets around to looking at the issue. We actively monitor critical parts of your server and our hosting facility and network to recover any problem before you even notice.
