I have a news site I check stuff for regularly..
Once in a while I can't access it completely from my 5 different browsers and even from the command line, nslookup cant resolve, ping and tracert fails.. All not being able to resolve the site name. The problem is specific to this one website.
I am told by the site support person that problem is that its cache on my machine or on ISP and I say that's not true because this site I access it 1-2-3 times a week from one browser only. I only fire up the other ones in times of trouble. And when i have the problem even if i try on my secondary machines i still get the same problems.
When the problem goes away, all works well. My question is: what's causing the intermittent dns/http problems. I don't believe this is something to do with my machine because the issue disappears without me having done anything at all.
