You have heard of Internet outages before from time to time, particularly in the first ten years the public was using the Internet. But what about a large Internet outage affecting massive numbers of websites in China? This week’s outage in China is taking many of the top Chinese Internet stocks lower and lower, and the outages were massive. The question to ask if this is too much of a drop or just the start. Maybe you can blame the weak purchasing managers report in China, but all in all tying web woes to web stocks is far easier to do.
