The web site you are trying to reach may not be appropriate.
The Department of the Interior (DOI) has policies governing the acceptable use of the Internet access. Specific guidance can be found in, at least, the following documents:
The World Wide Web is a dynamic and fast-changing place. If you believe the web page you are trying to reach is no longer classified correctly, you may notify the vendor responsible for classifying web sites for DOI by filling out the form located at: Submit A Site For Review. The vendor will review the information you provide and update system filters if appropriate. Please include the URL (e.g. http://website.com) you are attempting to reach.
If you believe this web site is categorized correctly and you have a legitimate business need to access it, please submit a request for exception to the Enterprise Security Officer, through your immediate supervisor to your Deputy DIO or higher authority. You may begin completing the unblock request by filling out the form located at: Submit An Unblock Request Form.
