   We are currently investigating an issue affecting the AEO Visibility & Analytics module. Some users are reporting that the module loads as a blank screen when accessed. As a temporary workaround, users may be able to access the module by: - Refreshing the page - Navigating away and then reselecting the AEO Visibility & Analytics module from the left-hand navigation menu The issue may not occur consistently and can be intermittent. We have identified that this functionality relies on a third-party integration and are actively working with the provider to investigate and resolve the issue as quickly as possible. We will provide additional updates as more information becomes available.

   The issue affecting the AEO Visibility & Analytics module has been resolved. The module is now operating as expected, and no further impact is expected.

   Podsumowanie: 16 lipca 2026 r. niektórzy użytkownicy na naszych platformach UE i USA nie mogli się zalogować przez około dwie godziny. Kwestia ta została spowodowana brakiem dostępu do uwierzytelniania przez stronę trzecią, co samo w sobie wywołało poważne problemy operacyjne w dużym dostawcy infrastruktury w chmurze. Usługodawca odrestaurował usługę poprzez zmianę trasy, a nasza platforma odzyskała się automatycznie. Nie było utraty danych i działań po naszej stronie. Przegląd incydentów: Wstępny krok naszych haseł i pojedynczych połączeń (SSO) jest obsługiwany przez dostawcę uwierzytelniania trzeciej strony. Kiedy usługodawca stał się nieosiągalny z powodu problemu infrastruktury w chmurze, użytkownicy próbujący tych podróży logowania otrzymali błędy uwierzytelniania. Ponieważ niepowodzenie leżało całkowicie w zewnętrznej zależności, nie było po naszej stronie żadnego elementu do naprawy. Dostawca ograniczył tę kwestię poprzez zmianę trasy ich ruchu z dala od dotkniętej infrastruktury, po której nasze podróże logowania odzyskały się samodzielnie. Impact: Password- based i SSO logins na platformach UE i USA były w większości niedostępne od około 2026- 07- 16T07: 55Z do 2026- 07- 16T09: 55Z. Użytkownicy wpisujący się przez bezpośrednie łącza nie zostały naruszone, a użytkownicy już zalogowani byli w stanie kontynuować pracę. Wykrywanie: Incydent został wykryty o godzinie 2026- 07- 16T07: 55Z przez nasz zautomatyzowany monitoring, który oznaczył dostawcę uwierzytelniania jako nieosiągalny i krótko po odebraniu nieudanych kontroli logowania w całej UE i USA. Odpowiedź: Nasz zespół operacyjny rozpoczął dochodzenie i potwierdził, że awaria była niepowodzeniem w trzecim dostawcą uwierzytelniania, który już opublikował aktualizację statusu potwierdzającą problem. Skontaktowaliśmy się bezpośrednio z dostawcą i potwierdziliśmy, że po naszej stronie nie ma żadnych działań naprawczych, ponieważ błąd był całkowicie w ich infrastrukturze. Przyczyna korzenia: Poważny problem operacyjny w dużym dostawcy infrastruktury w chmurze zakłócił routing naszego trzeciego dostawcy uwierzytelniania, co sprawia, że jest nieosiągalny. Ponieważ ten dostawca obsługuje pierwszy krok naszych haseł i podróży logowania SSO, te podróże nie powiodły się, gdy przerwa trwała. Kolejne kroki Podczas gdy ten incydent powstał całkowicie poza naszymi systemami, przeglądamy opcje mające na celu zmniejszenie wpływu wszelkich przyszłych przerw w uwierzytelnianiu przez osoby trzecie, w tym ulepszone ostrzeganie o ziarnistości wokół zdrowia dostawcy wyższego i opcje awaryjne dla ścieżki logowania. Prowadzimy również działania z dostawcą na własnych etapach rekultywacji.

5. 14 maja 2026 17:54 UTCpostmortem

   **Executive Summary:** On May 6, 2026, an infrastructure failure in our Kubernetes environment caused SSO login failures for a subset of users for approximately 42 minutes. All other platform functionality was unaffected. The issue was caused by a loss of quorum in an internal cluster's control plane, compounded by a node that had been silently degraded. The incident was resolved by replacing the affected nodes, and the system has been operating normally since. **Incident Overview:** The issue originated from an internal infrastructure cluster that acts as a connectivity bridge between our environments. Two of the cluster's three control plane nodes became non-functional — one had been in a degraded state, and a second failed during normal operations. With two of three nodes down, the cluster could no longer coordinate its workloads, which disrupted the network path required for SSO logins for some users. Some of our internal tooling was also affected. To resolve the issue, the team replaced the unresponsive nodes, which restored normal operations. Login functionality recovered shortly after. **Impact:** Some users logging into the platform via SSO experienced failures from approximately **2026-05-06T14:34Z** to **2026-05-06T15:16Z** \(~42 minutes\). **Detection:** The incident was detected at **2026-05-06T14:34Z** when our automated monitoring system identified connectivity failures in the login journey, which alerted the operations team. **Response:** Our operations team began investigating immediately. The affected control plane nodes were identified and replaced, with full recovery confirmed via automated tests at **2026-05-06T15:16Z**. A status page update was posted during the incident. **Root Cause:** Two of three control plane nodes in an internal cluster became unavailable at the same time — one had been silently degraded, and a second failed independently. The monitoring pipeline that should have detected the degraded node ahead of time was itself not functioning correctly. Because it only logged on failure and not on success, its silence was indistinguishable from normal operation, and the team had no way to know it had stopped working. Follow-up actions updated the monitoring pipeline to emit success signals so that their absence can be alerted on, improving overall control plane monitoring coverage, and introducing scheduled control plane node replacements as a preventive measure.

5. 14 maja 2026 17:55 UTCpostmortem

   **Executive Summary:** On May 1, 2026, users on our US platform experienced login failures and slowness for approximately 2.5 hours. The issue was caused by an internal service generating an excessive number of simultaneous requests to a shared backend component, which became overloaded and caused a cascading failure in the login process. The issue was resolved the same day, and the system has been operating normally since. **Incident Overview:** The issue originated from one of our internal data-processing services, which attempted to process a large volume of data for a single account all at once, rather than in manageable batches. This created an unexpectedly high load on a shared backend service that other parts of the platform depend on, including the component responsible for verifying user access during login. As the shared service became overwhelmed, the login-related service was unable to complete its checks and began failing repeatedly. This meant users trying to log in received errors or experienced significant delays. To resolve the issue, the team identified the service generating the excessive load and temporarily disabled it, since it wasn’t a real-time component. This immediately relieved the pressure on the shared backend, and the login process recovered shortly after. The service was subsequently restored with a fix applied preventing the same pattern from recurring. **Impact:** Users on the US platform experienced login failures or significant slowness from approximately **2026-05-01T14:46Z** to **2026-05-01T17:24Z** \(~2 hours 38 minutes\). The platform itself remained generally available for users who were already logged in. A status page update was posted during the incident. **Detection:** The incident was detected at **2026-05-01T14:46Z** by our automatic monitoring system, which alerted the operations team to login-related failures in the US environment. **Response:** Our operations and engineering teams began investigating immediately. Initial steps focused on scaling up the affected backend components and stabilizing the login service. Once the source of the excessive load was identified, the responsible service was temporarily disabled at **2026-05-01T17:06Z**, which resolved the issue. Login errors subsided within minutes, and the status page was updated to reflect recovery at **2026-05-01T17:24Z**. **Root Cause:** An internal data-processing service attempted to handle all data for an unusually large dataset simultaneously, without any limit on the number of concurrent operations. This generated a surge of requests that overwhelmed a shared backend service, which in turn caused the login verification process to fail. The service has since been updated to limit concurrency and prevent this pattern from recurring.
