But, when nothing changes after refreshing the page once or twice, you give up, mutter under your breath, and move on. Whatever the reason for a website crashing or slowing down, it's bad for business and for your online reputation.

However, according to at least one report only six people enrolled in Obamacare on the first day. Then shortly after, the entire website crashed along with its infrastructure.
