We use OpenDNS as yet another layer of security and control, as enforcement of our Acceptable Use Policy, as well as some phishing and malware protection. Today we suddenly found OpenDNS was returning perfectly valid IP addresses to queries for blocked domains, such as facebook.com.
I checked our settings and nothing seems amiss, and more disconcerting, I do not see anything on the OpenDNS site that gives any indicator that anything is wrong.
I would dismiss this as a hiccup or even something wrong on our network, but this is happening to two distinct networks and two distinct OpenDNS accounts.
In general I am fairly happy with OpenDNS and have used it for years, but rarely by itself, because, after all, it’s a DNS service in the cloud and neither should be trusted completely.
Hey there!
I’m a marketing manager at OpenDNS. While I can’t diagnose why this might be happening, we can definitely take a look at this if you send us a note here: http://www.opendns.com/support/contact/
Hope that helps!

Thanks Laura – I’m going to check to see if we are still experiencing the issue today, if so I will use your support contact link.
Strangely we have just had a similar issue here in the UK with Open DNS. Our equivalent of US Download/realtime rating was behaving badly and using Trace Route we identified Open DNS as possible problem. We forced the web portal address as allowed and are monitoring perfromance.
