Sorry if you get more than one copy of this.
We have been tracking some issues with the hardware for our primary database cluster, and we're going to start moving some of our databases to our other clusters over the next few weeks. While the data is being moved the affected services will be unavailable(read or write).
Currently the outages planned are as follows:

The outages are expected to last for at least of couple of hours.
