The food court (open area) has a lot of options. You sit down in front of Domino&amp;#x27;s (Facebook), since you want to eat garlic bread. Now, you can&amp;#x27;t order from the counter directly. The waiter will come to your seat and ask for the order. You ordered garlic bread from the waiter, but the guy at Domino&amp;#x27;s counter went missing. Your order was not reaching to the chef in kitchen as Domino&amp;#x27;s counter guy was not present.&lt;p&gt;This explains why Domino&amp;#x27;s (Facebook) ecosystem was down, but what about other vendors? They had nothing to do with Facebook.&lt;p&gt;To understand this, we need to go back to our food court again. Now, there are a lot of hungry people sitting outside Domino. Since they were not getting answer from one waiter as why their food is not on their table, they started disturbing all the waiters. Due to this, majority of the waiters were trying to figure out where the Domino&amp;#x27;s counter guy went and other food joints (read websites) were not able to fulfil their own orders.&lt;p&gt;So although only Domino&amp;#x27;s was down, it appeared as if whole Food Court (Internet) was facing issues.&lt;p&gt;Counter Guy at Domino&amp;#x27;s - Facebook Nameservers

The page somehow vanished and you don&amp;#x27;t know their address any more. So you start phoning other people and knocking on their door to try and find what their address is. Everyone else is doing this and no one knows what their address is. So you&amp;#x27;ve got millions of people phoning each other and knocking on doors.&lt;p&gt;Facebook being down was already an issue, but everyone phoning and knocking on doors was causing disruption to everyone else.</text></comment>
