Update timeline

  1. resolved Sep 17, 2026, 01:57 PM UTC

    Impact: From 14 Sep 18:14 UTC to 15 Sep 08:41 UTC, calls to POST /entities/{did}/address-ownership/discover on api.eu1.notabene.id timed out without a response. All other API endpoints, including transfer creation and authorization, were unaffected. Sandbox was unaffected. Customers using discovery as a step in their withdrawal flow saw those withdrawals held for the duration. Timeline - 14 Sep 18:14 — A network security rule permitting our EU production cluster to reach the internal address hash service was removed during infrastructure work. Discovery requests began timing out. - 15 Sep 08:21 — Customer reports received. Incident opened. - 15 Sep 08:26 — Root cause identified as a missing network rule. - 15 Sep 08:41 — Rule restored. Discovery recovered immediately. No backlog processing was required, as failed requests had not been queued. - 15 Sep 10:15 — Permanent fix to the infrastructure module merged.
