What the heck, i was really wondering why my site fails to load yet something small and hidden i never suspected before, while everything was working well on my development machine but i was getting error 503 on the remote production server running windows server 2008,
after a coffee mug i did what i should have started with and alas
on checking my application pools it had automatically stopped :(
on further research i understood its a kind of fail safe feature when your web application generates so many errors , iis 7 will just stop the application pool. i also noticed it had changed from automatic start = true, to false
anyway that iis for you, next time before you scratch your head check if your pool is up en running.
