Yes, it is frustrating to get blocked by our internet filter (Zscaler). But, there may be times when your research leads you to a site that you need. In that case, please use the Unblock Request Form. If I find that the page is full of great information for your research, I will unblock it and send you an email to let you know it's now open. Please give me at least a day to unblock a site for you.
