   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.

2. 2026年8月14日 8:13 UTCresolved

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

   エクゼクティブサマリー: 2026年7月16日、EUおよび米国プラットフォームの一部のユーザーは、約2時間ログインできませんでした。 問題は、大規模なクラウドインフラストラクチャプロバイダで主要な運用問題によってトリガーされたサードパーティ認証プロバイダで、停電によって引き起こされました。 プロバイダーは、トラフィックを再ルーティングし、当社のプラットフォームは自動的に回復しました。 データの損失はなく、その側で必要な行動はありませんでした。 インシデント概要:パスワードとシングルサインオン(SSO)のログインの初期ステップは、サードパーティ認証プロバイダによって処理されます。 上位クラウドインフラの問題によりプロバイダが到達不能になった場合、ログイン・ジャーニーが認証エラーを受け取りました。 故障は、外部の依存性に完全に座っているため、その側のコンポーネントは修理できませんでした。 プロバイダは、影響を受けたインフラからトラフィックをリルーティングすることにより、問題を軽減しました。その後、ログインの旅は自分で回復しました。 影響:EUおよび米国プラットフォームのパスワードベースおよびSSOのログインは、ほぼ2026-07-16T07:55Zから2026-07-16T09:55Zまで利用できませんでした。 直接リンクでサインインしたユーザーは、全体に影響を受けず、既にログインしているユーザーは引き続き機能できるようになりました。 検出: インシデントは、2026-07-16T07:55Zで自動監視で検出され、認証プロバイダはEUと米国の両方でログインチェックを失敗した後、到達不能かつ短時間でフラグを立てました。 回答:当社のオペレーションチームは、問題の承認を既に公表した第三者認証プロバイダで調査および確認を開始しました。 プロバイダーに直接連絡し、そのインフラ内での障害が完全にあったため、当社の側で利用可能な是正措置がなかったことを確認しました。 ルート原因:大規模なクラウドインフラストラクチャプロバイダでの主要な運用問題は、サードパーティ認証プロバイダのルーティングを中断しました。 そのプロバイダは、パスワードとSSOのログインの旅の最初のステップを処理しているため、その旅は、停電が続く間に失敗しました。 次のステップ このインシデントは、システム外で完全に発信されましたが、今後サードパーティの認証不足の影響を削減するオプションを検討しています。また、上流プロバイダーの健康とログインパスのフォールバックオプションに関する警告の粒度が向上しました。 また、自社の是正手順で提供者をフォローしています.

   **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. 2026年5月14日 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.

   We are currently investigating an issue causing delays with Siteimprove’s crawler and link checker processing. Sites are successfully entering the scan queue; however, some scans are taking longer than expected to complete. As a result, Digital Certainty Index (DCI) scores and related metrics may be delayed in updating. Our development team is aware of the issue and is actively working to restore normal processing. We will continue to provide updates here as more information becomes available.

2. 2026年4月30日 11:46 UTCidentified
