That's a good blog post. But "x is down" is newsworthy for sufficiently large number of users of x and sufficently long downtime. That's because consumer experience with this or that online service influences the online service's reputation. A service with few users, or users who have lower expectations, can endure more downtime without loss of reputation than a service with many users who expect the service simply always to be available, at least as available as broadcast television or plain-old telephone service.
