    Between 04:18 PM EDT (UTC -04:00) and 03:15 PM EDT (UTC -04:00), some customers hosted in North America, Asia Pacific and Europe experienced issues with list size calculation. This was caused by a race condition in list size calculation logic. Although aggregate values appeared incorrect during this period of time, no data was corrupted or lost. As of 03:15 PM EDT (UTC -04:00), we have corrected these calculations and the incident has been fully resolved. We apologize for any confusion and appreciate your patience while we corrected this.
