When most sites get something 99.99% right that's doing really good. Even your hosting company won't assure you 100% uptime. And how often has Twitter been down

When most sites get something 99.99% right that's doing really good. Even your hosting company won't assure you 100% uptime. And how often has Twitter been down? Or how many times has Facebook turned on a feature that everyone hated? Remember Beacon? It's easy to call foul on Google's mistake (and it clearly was a mistake), but it's easy to forget that we rely on Google's super-stable infrastructure and that infrastructure has fewer bugs and higher uptime than almost any other service. Picking out the Facebook login bug is funny, sure -- Google-bombing is always kind of funny. But saying that you know better than hundreds of the world's best engineers who've studied these problems for many years... well, that feels like hubris.
