After clearing my cookies and browser history as well as resetting my advertiser identifier in IOS, I was not able to visit Elitetrader.com and other non top 10 sites measured by traffic. However, Google loaded instantly. After google loaded, I opened another browser window, but still was not able to load Elitetrader.com and other non top 10 sites. Only after searching for Elitetrader on Google and clicking the link did Elitetrader load. I repeated the process of clearing my cookies, history, and advertiser ID and got the same issue. The wifi I was using at the time was City of Irving, TX Public Library.
