    I have the following domains in my domain block list, however, I recieve a "blocked domain" OpenDNS page (http://block.opendns.com/?url=www.nasa.gov) when I browse to "www.nasa.gov"...any ideas? I was told by OpenDNS that they noticed the problem, but never heard back yesterday (7/2/2007).

    Hi Rob, indeed nasa.gov is not in your blocklist, its not in any body's block list, so its rather puzzling that its being blocked, so that we can track this down in the logs, could you return the output of 'nslookup www.nasa.gov', along with the public ip of the machine making the dns request and the time range in which you did this?. It would help us track down the problem.

    Rob,

    It's on your blocklist:

    $ host www.nasa.gov
    www.nasa.gov is an alias for www.nasa.gov.speedera.net.
    www.nasa.gov.speedera.net is an alias for www.nasa.gov.edgesuite.net.
    www.nasa.gov.edgesuite.net is an alias for a1718.x.akamai.net.
    a1718.x.akamai.net has address 128.241.220.73
    a1718.x.akamai.net has address 128.241.220.90

    You have speedera.net blocked which means a lot of domains will be blocked.
    Thankful People: ahoier, Robert Haas

    Check your HOSTS file :)

    Perhaps someone has redirected

    nasa.gov to 208.69.32.135 (block.opendns.com :P)


    Note: oops, not his problem :) But it could have been a possibility :)

    Could the block page explain which block rule is applying to the domain, under a "Details" link or something that expands like the "contact your network administrator" link?

    I removed "spedera.net" from my block list over 24 hours ago and I am still getting the same block message about "www.nasa.gov". I've even tried this from multiple other systems on my network, all still bring up the blocked domain OpenDNS page.

    Also, I agree with mnordhoff above, it would be nice if the OpenDNS block page was more descriptive as to why the domain was blocked in some sort of "more details" link, etc. (i.e. The site was blocked because its alias or CNAME is in your administrator's "default blocked domains" configuration).

    speedera.net was still blocked in some of your networks. i removed it from all of your networks, please let us know if the problem persists.

    That would explain it then...I have to admit that I didn't check each of my networks. I did remove the "speedera.net" from the "View aggregate stats and manage default settings" option, and so I figured that it would remove it from all my networks.

    Thanks for your help.
