Do you have a website that just crashed, even though it had been working for weeks without any problems? This can be very frustrating, especially if you are using the website to sell items and you need it to work so that you can get customers. Every minute that it is down is a minute in which your traffic numbers are falling and you are losing out on sales. You need to get this fixed. The first step is to check and make sure that the site is really down and that it is not just your computer. You should go on another computer that you know is working and try to open up the site. There are rare cases in which the recorded information that your web browser stores as you surf the web can make it look like a site, which is actually functioning correctly, has crashed. Trying it on this new computer, with different information, will tell you whether or not this is the case.
If the site is still down and you have website hosting from Network Solutions, you should contact them to find out if there is a noted problem. Web servers do crash from time to time, and there is not much that can be done on your end. As long as the hosting company knows that there is an issue, though, they can work quickly to get it resolved, and your site will naturally launch again as soon as they are able to do so.
