2025 年 6 月 12 日，受 Cloudflare 中斷影響，`logto.app` 上的 Logto 服務請求路由一度受阻。事故很快被解決，數據安全和核心服務未受影響。
2025 年 6 月 12 日 18:07 至 18:58 UTC，通過 logto.app 網域（包括自訂網域）存取 Logto 服務的用戶遇到錯誤。服務中斷原因是 Cloudflare Workers KV 發生故障，影響到我們的路由層。直接使用 DNS 解析、並不依賴 Cloudflare Workers 的 Logto Cloud 服務及 Logto Console 不受影響。服務於一小時內恢復，數據安全未受影響。
logto.app 的請求開始返回 500 錯誤。本次事故由 Cloudflare Workers KV 停機引起。我們的 Cloudflare Worker 會將請求路由到每個租戶或網域對應的 Logto 區域，以確保合規與資料本地化。為提升效能，Worker 利用 KV 快取這些區域映射。當 KV 變為不可用時，快取操作失敗，Worker 拋出錯誤而非直接降級為無快取模式，導致服務中斷。

Logto Cloud 服務及 Logto Console 由於依賴直接 DNS 解析、不使用 Cloudflare Workers 路由，所以未受影響。
logto.app 存取 Logto 的用戶，約 50 分鐘內持續遇到錯誤。感謝你耐心等待與支持。
