 ## Overview
 
 This data source is based on the [COVID-19 Search Trends symptoms
 dataset](https://console.cloud.google.com/marketplace/product/bigquery-public-datasets/covid19-search-trends?hl=en-GB). Using
 this search data, we estimate the volume of searches mapped to symptom sets related
 to COVID-19. The resulting daily dataset for each region shows the average relative frequency of searches for each symptom set. The signals are measured in arbitrary units that are normalized for overall search users in the region and scaled by the maximum value of the normalized popularity within a geographic region across a specific time range. **Values are comparable across signals in the same location but NOT across geographic regions**. For example, within a state, we can compare `s01_smoothed_search` and `s02_smoothed_search`. However, we cannot compare `s01_smoothed_search` between states. Larger numbers represent increased relative popularity of symptom-related searches.

 ## Limitations
+
+Between May 13 2024 and August 6 2024, signal values were 25%-50% lower compared to previous time periods.
+This affected _all_ signals and symptom sets.
+The drop does not reflect actual search term popularity during the affected period.
+The apparent decrease in search volume was caused by an outage in the data pipeline on the source side.
+The data was unfortunately not recoverable and the dip can not be repaired, but data outside the listed time period is unaffected.
+
 When daily volume in a region does not meet quality or privacy thresholds, set
 by Google, no daily value is reported. Weekly data may be available from Google
 in these cases, but we do not yet support importation using weekly data.
