+## Issue Sort
+
+Change how issues are sorted in the issues stream by selecting from the sort dropdown:
+
+![Issue sort](issue_sort.png)
+
+- **Last Seen**: The most recent events are shown first.
+- **First Seen**: The newest issues are shown first.
+- **Priority**: New issues and escalating issues (with event volumes trending upward) are shown first. Older issues and issues with fewer recent events are sorted lower. The ranking currently relies on three primary factors:
+  - Relative volume: Escalating issues that have a higher recent volume (relative to their baseline) are ranked higher.
+  - Absolute volume: Issues with more event volume are weighted more highly. Recent events are weighted more than old events.
+  - Issue age: New issues are prioritized — an exponential decay factor halves the weight every 12 hours.
+- **Events**: Issues are sorted by total event volume.
+- **Users**: Issues are sorted by number of users affected.
