What about visitors to my experiments currently running on these browsers?
It will appear as if the experiment has stopped and no Optimizely experiments are running on the page.
What about my data?
Our data indicate that IE 6 & 7 form a negligible fraction (~0.2%) of traffic to almost all of our customers’ sites.
You may see a change in results in the unlikely scenario that you have an unusually high percentage of traffic from these two browsers AND an experiment running for which a variation performs differently only on these two browsers. In this scenario, using browser targeting in Audiences to exclude IE 6 and 7 for any experiments that will be active on October 15 will avoid any discrepancy.
