微軟Xbox首席技術官史考特·范·弗利特（Scott Van Vliet）於8月10日在X平台發文，就近期Xbox Live大規模服務中斷事件作出正式說明。據科技媒體Windows Central報道，此次故障持續超過一天，波及全球多個國家和地區的Xbox玩家，影響範圍之廣、時間之長，堪稱該品牌近年來最嚴重的在線服務事故。
(sigh) It’s been like this for a while now. Apparently @XBOX Live is down in Finland or something. Kind of sucks. I wonder if @XBOXSupport can tell anything relevant?
@XBOXSupport cannot connect to Xbox live AGAIN through a backwards compatible game. How many times is this going to happen this year? @XBOX
故障期間，用戶不僅無法訪問在線多人遊戲、雲存檔等聯網功能，就連已下載的數位版遊戲和實體光碟遊戲的授權驗證也一度失效，大量玩家陷入無法啟動任何遊戲的窘境。弗利特解釋稱，本次宕機的根本原因在於微軟對底層許可服務進行了更新——該服務主要負責支撐Xbox Home Console sharing（家庭主機共享）、Xbox Game Pass已購內容以及PC端相關授權場景。更新推送後，這些依賴項因兼容性問題進入無響應狀態。
I wanted to provide an update on the incident affecting some players trying to launch games and access other game library features last week. What was the root cause? As I previously wrote, an underlying service required for XBOX Home Console sharing and Game Pass purchased content, as well as some PC scenarios, experienced an outage whereby an update to the system put some services in an unresponsive state. This was compounded by a bug in the XBOX client software stack, which caused other license checks to also fail when that first service went down. These two issues created some cascading failure scenarios that affected some players' ability to launch games and causing cascading issues with library enumeration. What have we done about it? We are transitioning ownership of the underlying licensing service to the XBOX team while our engineers are actively hardening the services and infrastructure for future updates. The client bug has been fixed in an upcoming release, which starts rolling out today, August 10, and becomes mandatory August 17. What comes next? Our engineering and operations teams are looking broadly across our stack to improve reliability of our products and services. We will have more updates to share in the weeks and months ahead as we roll out some great new features for players, paired with quality-of-life systems updates. Thanks for playing!
與此同時，Xbox客戶端軟體棧中還存在一個獨立bug，導致其他數位版遊戲的許可檢查失敗。兩類問題相互疊加，故障如多米諾骨牌般迅速擴散，最終造成大面積服務癱瘓。為解決隱患，微軟已制定兩項關鍵應對措施：一是將該底層許可服務的所有權正式移交至Xbox團隊，並由工程部門持續優化Xbox Live基礎設施，確保未來更新更加穩健;二是針對客戶端bug的修復補丁已開始推送，並計劃於2026年8月17日轉為強制下載，所有玩家屆時必須安裝。
弗利特同時表示，微軟將繼續推進新功能開發和系統體驗優化，並始終將產品與服務的穩定性置於優先位置。他承諾，團隊將從此次事件中吸取教訓，進一步完善更新流程和質量管控，避免類似大規模宕機再次發生。
