What if a meteor levels Redmond, and the only server backup is in Singlish? We can imagine all kinds of troubling scenarios, but it only serves to raise our cortisol levels.

It's not a big deal to move the authorization server to another host, and most of those plugins that you might need to reauthorize down the road are still going to be active products for sale. They are not going to be Kjaerhused.

At least until the next meteor shower.
