Found an issues with my companies external DNS yesterday that I would be curious to know how long it has been a problem. Our external DNS for my website had 5 name servers listed on the root DNS servers, 2 out of these 5 did not work. So theoretically all pages loads could have been taking a lot longer to load. In some of the testing I ran it would try to hit the first server that didn’t work then went to the 2nd server that didn’t working until is finally found a third server that could resolve the domain. This issue has been resolved now I am hoping; unfortunately I cannot look at it myself because another person in the department is in charge of DNS and does not share any info on it. From what I have seen on this DNS setup it is one big spider web and no-one really knows if all pieces are setup the same, let alone right. To the business I happen to work for this could be detrimental to the company since we rely on web traffic so heavily. It is my opinion that DNS is a very simple concept and should be very easy to setup right but without the access into the system my hands are tied. I get very frustrated when I know I can fix something or at least improve on it but am never given the chance.
