The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage. A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe, and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative. Not all providers release uptime statistics. Most hosting providers will guarantee at least 99.9% uptime which will allow for 43m of downtime per month, or 8h 45m of downtime per year.
In addition to looking up a domain by IP, Whois lookup can also help you validate your website code with one of several Domain and SEO tools including CSE HTML validator, W3C HTML validator and the CSS Validator. Each WhoIs tool identifies errors in your source code so that you can fix things like missing closing tags, errors in character encoding and more. No matter what DNS information you are looking for, WhoIs can help you identify anything related to domain names quickly and easily.

In order to publish your website online, your business website requires a web hosting service. However, a web host gives business owners more than just web hosting services! For example, web hosting firms typically employ in-house technicians to make sure their clients' websites are up and running 24/7. Plus, when website owners are in need of help or troubleshooting (e.g. script debutting, email not able to send/receive, domain name renewal, and more), the web host's in-house support are the go-to people. A professional web hosting service ensures a hassle-free experience for business owners, so they can efficiently focus their time and effort on their businesses.
