We have finished preparing the new Cassandra cluster and are already running live data into it without issue. Once we have completed validating the new cluster, we will cut over to it. At that point, charts in the web application will function properly. We will also begin loading historical data into the new cluster and that will start loading in over the next few days.
Please continue to check this blog for status updates as we progress. As always, we apologize for the interruption of service and are working hard to rectify the situation.
