Yesterday Facebook, WhatsApp, and Instagram all took a powder on a global scale.
When I went to Facebook, it was a 404, when I went to Instagram, I had what last loaded with a cute message saying it can’t load new items, but all my old ones were cached so I could go check them out. I didn’t bother with WhatsApp.
The question isn’t about which one handled it better, which was more graceful or did a better job of keeping their customers up to date as to what was happening.
The question is what will your app do on it’s worst day and how will your customers get by.
