Did you know that our primary datafeed circuit went out last week? Betcha' didn't even notice. The reason is that our secondary circuit immediately kicked in and kept everything running smoothly. Prior to last fall's datafeed upgrade, that would not have happened and the site would have been down for several days. That secondary circuit is just one more example of the (mostly hidden) improvements we've been working on to ensure that StockCharts.com continues to serve the best charts on the Internet.
