The Internet Traffic Report monitors the flow of data around the world. It then displays a value between zero and 100. Higher values indicate faster and more reliable connections. Your Internet surfing safari may be smooth today, but perhaps you can't reach Yahoo or a few web sites in Europe. This informative web site will tell you if those regions of the Internet are currently slowed down. By checking the Internet Traffic Report, you can determine if your problems are global or local. This site updates its statistics every 15 minutes.
