I don't quite understand this one? Does it refer to domain name server? So if you're having network issues it's always DNS problems?

I never cut-and-paste directly from stack overflow. I cut from several sources, combine the best practices and adapt everything to make something novel, and hopefully "better". But i think it's important that you understand what it does before you use it. This might seem self-evident, but my experience tells me not everyone agrees with this methodology. If i find inspiration to a solution, i usually leave a link to the original source or stack overflow page.



The DNS part is a joke (I guess?) about how unreliable and surprising DNS issues can be. You could do the same with caching.


Oh certainly. In fact, caching issues (on multiple levels) is a constant pain in the ass in my line for work anyway. It can be so subtle sometimes that you spend hours looking at something that shouldn't be an issue. But it is, and i think we all know why.
