And BOOM, suddenly you find out that the large instance on AWS, cannot handle the traffic, you are befuddled its not like the server is getting million hits/sec. You thought a large server would be enough to handle a single wordpress blog, and you realize that's not the case.
Now you go back and start fixing your self hosted wordpress blog, you feel sad that you missed out on audience because the server crashed, your work gets derailed because now you also have to maintain the blog server.
I agreed I too would have been irritated to see the link not working, but its not that you switch to an x-large instance each time you post a link on HN. Sometimes you just want somethings to work. But alas that's not the case.
