OpenDNS and this forum? - Tech Support Forums

I use OpenDNS and I found that the site isn't loading as shown in the picture. Yet I use a proxy and it does work. What gives?

Well it partially works, but I think an image server is down.

We enacted some DNS changes earlier this week. However, third-party DNS issues are beyond the control of TechIMO.

I have OpenDNS in my DNS chain when connected via DSL at home, but it is alongside my ISP DNS servers as well. Then again, I also run a local installation of the BIND DNS server instead of using Windows DNS caching.

Update: While not specifically related to DNS resolution, there are few files apparently missing on the image server. I have filed an error report.

That's understandable.

So you add your ISP's DNS servers in the network adapters list, correct?

Lucky you.

The image server was down for 10 hours this morning but has been fixed.

Correct. Well, to be technical, those settings are then automatically migrated to my localized BIND install, but anyway, they will work with the standard Windows DNS service as well.

You can actually add several DNS servers if desired. Just verify the ping times to those servers are relatively low, and I suggest using only trusted and verifiable servers.

For example, I typically use one local DNS server - a customized version of BIND - plus five upstream DNS servers: three ISP and two OpenDNS.

That was what I thought. On another forum that I'm a member of they had the same issue. It turned out to be a T1 line down or something. I wonder, was that the case here too?

I actually don't know any other DNS server besides my ISP's and OpenDNS's.

Those will be the ones I'll enter into the network adapters. I found OpenDNS server's to be a little faster than my ISP's ping time. I will be adding my ISP's to the list so that site's can resolve if the DNS ever changes again. I guess it makes sense that OpenDNS didn't catch the change right away or something.

Oh, I wasn't sure where to post this because I don't really see an Admin/help section.

I take that back. I found my ISP's first DNS to be 11ms compared to OpenDNS's to be 56 ms.

Just verified that through the router's ping tool as well.
