   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.

   Résumé: Le 16 juillet 2026, certains utilisateurs de nos plateformes européennes et américaines n'ont pas pu se connecter pendant environ deux heures. Le problème a été causé par une panne chez un fournisseur d'authentification tiers, qui a lui-même été déclenchée par un problème opérationnel majeur chez un fournisseur d'infrastructure de cloud. Le fournisseur a rétabli le service en reroutant leur trafic, et notre plateforme a récupéré automatiquement. Il n'y avait aucune perte de données et aucune action requise de notre côté. Aperçu de l'incident: L'étape initiale de nos trajets de connexion par mot de passe et par connexion unique (SSO) est gérée par un fournisseur d'authentification tiers. Lorsque ce fournisseur est devenu inaccessible en raison d'un problème d'infrastructure cloud en amont, les utilisateurs qui tentaient ces parcours de connexion ont reçu des erreurs d'authentification. Parce que l'échec était entièrement dans une dépendance externe, il n'y avait aucun composant de notre côté à réparer. Le fournisseur a atténué le problème en éloignant leur trafic de l'infrastructure touchée, après quoi nos parcours de connexion se sont récupérés. Impact: Les connexions basées sur le mot de passe et SSO sur les plates-formes de l'UE et des États-Unis étaient pour la plupart indisponibles entre 2026-07-16T07:55Z et 2026-07-16T09:55Z. Les utilisateurs qui se sont inscrits par le biais de liens directs n'ont pas été touchés et les utilisateurs déjà connectés ont pu continuer à travailler. Détection : L'incident a été détecté à 2026-07-16T07:55Z par notre surveillance automatisée, qui a signalé que le fournisseur d'authentification n'était pas accessible et peu de temps après a ramassé des vérifications de connexion défaillantes à travers l'UE et les États-Unis. Réponse : Notre équipe opérationnelle a commencé à enquêter et a confirmé que l'échec était une panne chez le fournisseur d'authentification tiers, qui avait déjà publié une mise à jour du statut reconnaissant le problème. Nous avons communiqué directement avec le fournisseur et nous avons confirmé qu'il n'y avait aucune mesure corrective disponible de notre côté, car la faute se trouvait entièrement dans leur infrastructure. Cause fondamentale: Un problème opérationnel majeur chez un grand fournisseur d'infrastructure cloud a perturbé le routage de notre fournisseur d'authentification tiers dépend, ce qui le rend inaccessible. Parce que ce fournisseur gère la première étape de notre mot de passe et de notre connexion SSO, ces voyages ont échoué pendant que la panne a duré. Prochaines étapes Bien que cet incident ait pris naissance en dehors de nos systèmes, nous examinons les options pour réduire l'impact de toute interruption future de l'authentification par des tiers, y compris l'amélioration de la granularité de l'alerte autour de la santé du fournisseur en amont et les options de repli pour le chemin de connexion. Nous poursuivons également avec le fournisseur sur leurs propres étapes d'assainissement.

5. 14 mai 2026 à 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 mai 2026 à 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.
