DNS is broken i think...

DNS issue

so i am new to DNS, here is my problem

we have a marketing site hosted, externally the site works perfect however lately internally when we hit the url we get page cannot be displayed, the fix is to go to our DNS servers and clear cache which works for about 30 minutes then it breaks again

Post your domain name.

Better to know for sure (testing tools), than guess.

www.perksatwork.com - it works fine externally but internally there is the problem, sometimes the page does not load or the pics does not load

The network capture will show what response the client gets.

Thanks Mash, is this affecting all Cisco Umbrella customers or only a particular set?
