What if GAE breaks? Backup server strategies?

[Tom Campbell]

Preparing to charge people for my Python/web2py-based online scheduling/membership app. Am concerned about GAE downtime. Incidents like this and this concern me. What is the best way to be ready for GAE outages? Some hosts, for example, let you sign up for geographically distinct locations, which sounds great to me.

Prices are so low of course I'm quite willing to open multiple accounts, or allocate servers in different regions--whatever it takes. Let us also assume I am backing up data every few minutes to an hour.

What are best practices to prepare for a downed GAE server?

You can sign up for EU hosting. When you create your project under 'Show advanced options...' you can specify a location. You don't need multiple accounts just multiple projects under your account. Just note that any datastore information is not accessable between projects unless you use the remote_api. To help with downtime always code defensively. Wrap all RPC calls in try-catches with built in back offs.
