Timeline (UTC)
2022-06-02 15:58: Xandr teams deployed a repair to a third-party log aggregator.
2022-06-03 04:45: Budget pacing data stopped being published.
2022-06-03 11:47:00: Xandr teams rolled back the change.
2022-06-03 23:55: Budget pacing history resumed publishing as expected.
Cause Analysis
An issue with budget pacing data records was compounded when the third-party log aggregator that handles fallback data failed, resulting in missing data. The database itself was decommissioned, so the specific root cause could not be determined.
Resolution Steps
A database change suspected to be the root cause was reverted.
Next Steps
Xandr teams will enhance monitoring and procedures, and will continue to investigate to ensure greater database resilience.
