  4. resolved Apr 09, 2026, 04:45 PM UTC

    We identified and resolved the cause of elevated latency and degraded performance. A newly enabled internal process for synchronizing tax filing data generated significantly higher database load than expected, impacting API response times from ~9:15am - 9:38am ET. The feature flag has been reverted and system performance has returned to normal.
