Google App Engine is down

It's fine, because they're at 100% availability. Just totally down: http://www.evernote.com/shard/s2/sh/64201bd8-5392-49fc-a47c-...

I'm surprised that their status system seems to run off the main infrastructure too. Everyone else gets slated for making that mistake.

Are there any businesses currently using multi-cloud infrastructures? Ie. Automatic failover from Amazon to Heroku?

so is developer.android.com.
