An unusual cache condition allowed null values to be returned from “percentage change_*” properties in some API responses between 2019-05-17T18:30:00.000Z and 2019-05-17T21:30:00.000Z. This affected cryptocurrency-related endpoints where a non-USD fiat conversion was requested. Additional measures were put in place to prevent this scenario. Historical data was not affected.
