Business websites need to be online 24 hours a day because someone very wisely said that there’s no time fix time of death and a customer, they can arrive at any time. Keeping in view this sentence you have to ensure the best uptime guarantee from your Business Web Hosting Provider so that you don’t lose a client because of your website being down and not available.
Most of the web hosts offer 99.9% uptime guarantee but you have to ensure personally by keeping a record of your sites’ uptime. There are several good online services that offer to monitor the uptime of your website. You may like to test the free service of Uptime Robot to monitor the uptime of your business website. This is one of the best website I came across for this purpose.
To ensure the availability of your website to the customers you should also monitor it personally. If you are using dedicated server hosting then the things may be somewhat easier for you because the dedicated servers are mostly looked after more efficiently. Of course the price is on the higher side but it does offer certain additional benefits that may help you to remain active and available to your clients for most of the time.
