Re: wth is it with always dns?
In my experience it's most often non-technical people including management who suggest "it'll be the DNS", often because that's the one technical thing they've heard of and they want to sound like they know what they're talking about.
Certainly among my colleagues whenever we refer to "it's always DNS" we're not seriously suggesting that it is, we're taking the piss out of former bosses who insisted that may be the cause of any issue.
