# Daily drop and spike warnings now use the anomaly model

Daily drop and spike warnings are now computed with the daily-volume anomaly model. Since September 29 the event's traffic tab draws the expected volume and the drop and spike levels.

Daily drop and spike warnings are now computed with the anomaly model of the daily volume: the expected volume for that day of the week, and how far the real volume strayed from it.

**Update, September 29:** the traffic tab of an event draws the expected volume and the drop and spike levels, so you see why a day raised a warning and why another did not.

**Who it is for:** anyone who was tired of a Monday warning on a Sunday volume.

**Where:** the warnings of every event, and its traffic tab. Docs: [Warnings and updates](/docs/warning-and-updates).
