It&#x27;s a display problem. The spike appears at 2015-09-08 12:00ish, but is not visible at the same time on the shorter timescale views.<p>Edit: yes, it&#x27;s aggregating things incorrectly at 14+ days. Some parts of the graph appear to be &#x27;aggregate&#x27; (spike), others appear to be &#x27;average&#x27; (low points).
