My ISP's DNS server is Great, but now I'm wondering about where my website is hosted. Is this an issue? Is there a way to test it?

I had no idea what a DNS server was. Now I know and mine are working "GREAT".

For the record, I ran the test and had no difficulties: it worked GREAT! ;-)

I tried using the test link and received the message, "The requested URL could not be retrieved
---
While trying to retrieve the URL: http://c5daea0164e51ed4f806e1d3.et.dns-oarc.net/

The following error was encountered:

Unable to determine IP address from host name for c5daea0164e51ed4f806e1d3.et.dns-oarc.net
The dnsserver returned:

No Address records
This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
Your cache administrator is support.

From the preceding notes, I guess I'm not the only one having problems with the link, but the message seems different than others reported.

I tried to use the test; however, all I got was "Failure to connect to Web Server". Didn't matter what time of day. Would this be a Hughesnet thing?

For Teresa: The DNS problem does affect Macs. The problem is an Internet networking thing, so it affects ALL computers on the Internet.

Ran the test and received a result of Nominum. Is this company proven to be safe or is more time needed to tell? Better to use OpenDNS in the meantime or just sit tight? Thanks!

My ISP showed good at first test then on the 2nd try showed poor (just a straight line) on the first graph. Called them and they were unable to resovle the address on your e mail.

Am I to assume this DNS test will not work on a Mac?

DNS, and the test, is platform independant. It should work.

Sorry, I supplied the wrong text on my last email, it should have read:

The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings. "

Not that it could not find the server. My apologies.

Eld.

Also, I did look at the OPEN DNS info and realized I have not heard why I might not want to stay with it if I choose to switch, and why I might want to switch, DNS issue or not. It looks pretty inviting, but how do they make their money?

Thanks,

Eld. (Orwell Lives!)

one little difficulty I just experienced, and I'm sure I'm not alone... " Address not available" reply...Hum...Just too many people testing their DNS or has someone disabled the link...or, has my ISP (rogers) blacklisted the address...

Great! I was just about to ask you that. :)

My current ISP's DNS servers are not vulnerable but the ISP I am about to switch to is vulnerable (I made a friend run that test). So I would inform them.

But my question is how difficult a thing it is for them to apply the patch? Is it just like software updates (or maybe a little more complex) or is it really truly complex thing that an ISP might not have the expertise to implement in reasonable time?

It'll vary based on exactly which DNS server they happen to be running, but the bottom line is that it should be very easy, and even if it's not this is exactly what we expect our ISPs to be capable of doing and doing well.

FWIW: I updated my DNS server in less than a minute with two, maybe three clicks of a mouse. (Ubuntu Linux) Not all are that easy, but many are.

As I said there's no excuse.
