Web site downtime is the most unwanted word for web masters and the web site owners. So what is downtime in the internet? It is the time that your web site is not available when the domain name is typed in the internet browser. There are some monitoring companies that are watching all the web sites and used to count the outage time and report it as downtime. If you are web site owner or web mater you can join these kinds of web monitoring companies and when your web site is down they will send you e-mail notification immediately to your e-mail account about the web site outage. They offer free membership account and paid membership account service for these kind of information.
Some web site hosting companies regularly have this downtime problem but they are used to advertise that their web hosting service is the best hosting and 99.9% uptime. So as a web site owner or webmaster it is your duty to check those words from the other web site owners to check about their reliable service.
Also the downtime may occur when you transfer your domain name and the files to another web hosting and the DNS changing may take between 24 - 72 hours of time and your web site will have its downtime between these hours. This can't be avoided but can be minimized if you follow the instructions of the new web host carefully. Some time you may not see your web site even if it starts to work properly. So in those times ask your friends in the other countries to check the availability of your web site in the internet. Also you can use CGI Proxy service web sites like S, which will show your web site once it is available in your country.
You can use the Ping program to find out about your web site in the new hosting company. But we suggest CGI Proxy service as the best to reach and find out about your web site.
