DNS Blackhole Service

Beginning in Spring 2010, Clarkson University began actively blackholing DNS queries for sites that distribute viruses, malware, and other malicious content. Shortly after the implementation of this system, sites distributing advertisements and tracking cookies were added to the blackholing mechanism. The majority of the campus community has responded very positively to this system, as it improves the web browsing experience and increases the security of campus computers.

If you experience a problem accessing specific content that you believe is being blocked in error, please contact the Service Center to report the problem. If you need to access advertising (or other blocked content) on a regular basis, it is recommended that you use an alternative DNS service like OpenDNS or Google DNS.
