      Eメール通知で問題を識別し、それを解決するために修正を適用しました。 状況を監視し、安定した状態を維持し、追加の問題を検知します。 過去数日間に、DRACOONからのメール通知が届かない場合もございます。 ほとんどの場合、メールが受信メールを受け入れる前に特定のDNSチェックを含む特定の企業メールセキュリティゲートウェイを介して実行される組織が影響されます。 根本的な原因は、通知の送信者ドメインに影響を及ぼすサードパーティのDNSの問題で最も可能性が高いです。 通知は、再び配信されるべきです。 問題が完全に解決されると、配信を密接に監視し、更新を投稿します。 この期間中に配信されていない通知は、自動的に再送信されません。 ご迷惑をおかけいたしますが、何卒ご了承くださいますようお願い申し上げます.

      **20 - 26 10月2026日: ポストオルテム** 10月20日(火)〜10月26日(日)のメール通知にてお知らせいただきました。 私たちのチームは、根本的な原因を特定し、解像度を実装するために徹底的に取り組んできました。 このポスト・モテムでは、何が起こったのか、なぜそれが起こったのか、それを解決するために何をしたのか、そして今後同様の出来事を防止するために何をすべきかについて詳細を共有したいと思います。 **何が起こったのか?** この期間中は、DRACOONからのメール通知を受け取っていませんでした。 主に、特定の企業メールセキュリティゲートウェイを介してメールが実行される影響を受けた組織の問題。 これらの受信者に対して、多くの通知が拒否され、配信されません。 他のDRACOON関数は影響を受けません。 **こんなことがあったの?** メールを受信する前に、送信者のドメインが有効であることを確認するメールセキュリティゲートウェイがいくつかあります。 サードパーティプロバイダが運用するDNSサービスは、通知送信ドメインの構成の一部に誤った回答を与え始めました。 そのため、これらのゲートウェイは、送信元ドメインを無効に処理し、通知を拒否しました。 弊社独自の構成とメール配信サービスが全力で正しく機能しました。 **何をしたの?** 最初の顧客レポートの後、弊社メール配信パートナーと配送ログを分析し、拒否がクリアなパターンに続くことを確認しました。 サードパーティのDNSの問題にそれらを追跡しました。 10月26日、通知送信元ドメインの構成を変更し、影響を受けた第三者サービスに依存しないようにしました。 変更後、納品を正常に返し、問題が解決されたことを確認するために密接に監視しました。 **改善にはどうしたらいいですか?** ※外部サービスの依存関係を除去するために、メール関連の設定を見直しています。 ※メール配信のモニタリングを改善し、異常な拒否率が検出され、早期に調査されます。 ご迷惑をおかけいたしますが、何卒ご了承くださいますようお願い申し上げます。 当社は、当社のサービスの安定性と信頼性を確保し、今後同様の事故を防ぐための積極的な対策を講じています。 ご質問やご不明な点がございましたら、サポートチームまでお気軽にお問い合わせください.

      We experienced an issue with our Virus Protection feature on 13.08.2025 at around 12:00 CEST. Our team has worked diligently to identify the root cause and implement a resolution. In this post-mortem, we want to share the details of what happened, why it happened, what we did to resolve it, and what we will do to prevent similar incidents in the future. **What happened?** At 12:00 CEST, monitoring alerted the team about increased latency in the Virus Protection service. Investigation revealed that unusually high load from a spike in file scanning requests overwhelmed the systems processing capacity, leading to degraded performance for a subset of customers. **Why did this happen?** The Virus Protection service was able to keep up with the increased load for scanning files, but the responses were not processed fast enough by another service, leading to missing/delayed verdicts for the files that had to be scanned. **What did we do?** The team manually scaled out the service to restore capacity. At 15:45, latency metrics returned to normal and the functionality was fully restored. **What can we do to improve?** We are investigating the root cause of the slow response processing and will reconfigure the service in question to make sure to eliminate the bottleneck. We apologize for any inconvenience this incident may have caused. We are committed to ensuring the stability and reliability of our services and will continue to take proactive measures to prevent similar incidents from happening in the future.

In this post-mortem, we want to share the details of what happened, why it happened, what we did to resolve it, and what we will do to prevent similar incidents in the future. What happened? DRACOON Cloud experienced performance degradation. Some users reported slow response times and connection timeouts during the incident window. Why did this happen? The incident was caused by increased load and scaling issues. A part of the system was unable to handle the traffic volume, leading to resource exhaustion and subsequent service degradation. What did we do? Our team immediately identified the scaling bottleneck and implemented emergency load balancing measures. We scaled up the infrastructure resources to restore normal service levels by 15:40. What can we do to improve? We will implement automated scaling policies to handle traffic spikes, enhance monitoring and alerting systems for early detection of load issues, and conduct regular capacity planning reviews to prevent similar incidents.

    4. 2025年9月9日 15:33 UTCpostmortem

      We experienced an issue with Office file previews on 2025-06-25 from around 09:00 to 13:40. Our team has worked diligently to identify the root cause and implement a resolution. In this post-mortem, we want to share the details of what happened, why it happened, what we did to resolve it, and what we will do to prevent similar incidents in the future. What happened? We experienced an issue with office file previews, making the feature unavailable for all users. Why did this happen? A recent update of the license key used by our backend service responsible for the office previews did not work as expected, even though the same update has been working on our Staging environment. What did we do? We immediately investigated and identified that the updated license key was causing authentication failures in production. We got in contact with the service provider to solve the issue as quickly as possible. What can we do to improve? We identified the issue that lead to the discrepancy between production and staging environment and made sure this will not happen again in the future. We apologize for any inconvenience this incident may have caused. We are committed to ensuring the stability and reliability of our services and will continue to take proactive measures to prevent similar incidents from happening in the future. If you have any questions or concerns, please don't hesitate to reach out to our support team for assistance.

    4. 2025年9月9日 15:18 UTCpostmortem

      We experienced an issue with DRACOON Cloud on 2025-03-31 from around 07:30 to 08:15. Our team has worked diligently to identify the root cause and implement a resolution. In this post-mortem, we want to share the details of what happened, why it happened, what we did to resolve it, and what we will do to prevent similar incidents in the future. What happened? DRACOON Cloud experienced performance degradation during early usage hours, affecting user access and normal operation. Why did this happen? Application containers hit memory limits during high traffic periods, causing automatic restarts and service interruptions as the container orchestration system cycled through unhealthy instances. The memory limits were set too conservatively and hadn't been updated to account for certain traffic spikes. What did we do? Our engineering team quickly identified the container restart pattern through application logs and monitoring dashboards. We immediately increased the memory limits for affected services and scaled up the number of container replicas to distribute the load. What can we do to improve? We will improve our monitoring, update memory limits based on actual usage patterns, and create automated scaling policies that proactively increase resources before hitting limits. We apologize for any inconvenience this incident may have caused. We are committed to ensuring the stability and reliability of our services and will continue to take proactive measures to prevent similar incidents from happening in the future. If you have any questions or concerns, please don't hesitate to reach out to our support team for assistance.
