We will be bringing our main database offline for about 30 minutes tomorrow night starting around 10PM EST (03:00 GMT). You won’t be able to login to your account during this maintenance window. However, you’ll still be able to use the web app and the iOS/Andrdoid apps just fine, provided you’re already logged in. Your data will resume syncing with the cloud (and between your devices) once we bring the database back online.
Sorry for the interruption. We’ll post updates on twitter @nirvanahq to let you know when we start and when we’re done.
