I had packet loss occurring where a business was using the OpenDNS servers. When pinging the website ip no packet loss while pinging the name there was severe packet loss. Changed the DNS servers to the ISP's and the problem went away. The problem were intermittent emails being returned.

Maybe not a good idea to have OpenDNS * * in D7 until the issue is resolved?

All DNS servers seem to have issues from time to time. Some people will stick with OpenDNS regardless of whether or not I include it (pre-defined) in D7, but it's not like it's the only choice!

Does the site have an onsite DNS server? If so I'd setup the forwarders to OpenDNS and allow the local DNS cache local requests. This should help reduce this issue once the site has already been resolved. If not, are you using OpenDNS for content filtering? If not then I'd recommend using either the ISP's or Google (, DNS servers. I personally use Google DNS for everything, I've had excellent experience with them over OpenDNS for stability and performance.

Thanks for the feedback.

Question please, I am not a networking guru. When you use a public dns, such as Google, you know they are using your data to profile you and create better advertising algorithms. Why else offer it for free. So when you use these surf anonymously programs to block your ip/id, does this affect Google's data collecting attempts? Not really sure how these surfing anonymously programs are protecting me, if they are at all. Just curious. Thanks
