Business Verification vendor failure

Incident Report for Sardine AI

Postmortem

Summary:

On January 14, between 22:42 UTC and January 15, 19:07 UTC, we experienced an issue preventing US KYB enrichments via the Businesses API.

What Happened?

Our third-party data provider for US KYB enrichment deployed an update to their API that inadvertently rejected status update requests that were previously valid. This caused our enrichment process to fail for new businesses.

While our automated monitoring systems detected the error rate spike immediately, the resolution required intervention from the provider's engineering team, which extended the duration of the incident.

Why Did it Happen?

The provider introduced a strict validation logic preventing us from keeping the business status up to date. Our system, which ensures data consistency by confirming status, was blocked by this new rule.

What Are We Doing About This?

  • The provider has rolled out a fix, and services are fully restored.
  • We have backfilled the missing data for affected businesses.
  • We are actively working with the provider's engineering team to improve their change management communication to prevent unannounced API changes in the future.
