Microsoft が提供する Microsoft 365 のサービス正常性（MO402741）にて、複数のユーザーが Microsoft 365 サービスを利用できなくなる SI（サービスインシデント）が発生しています。

本事象の影響を受けているユーザーでは複数の Microsoft 365 サービスを利用できなくなる可能性があり、以下の問題のうち、1 つ以上で発生していた可能性があります。

また、その他の機能にも影響が発生していた可能性もあります。

・Microsoft Teams（アクセス、チャット、通話、会議、および Microsoft Teams Room デバイスでの会議への参加に関する問題）
・Exchange Online（メール送信の遅延）
・Microsoft 365 管理センター（アクセスできない）
・複数のサービス内の Microsoft Word（読み込みができない）
・Microsoft Forms（Microsoft Teams 経由で使用できない）
・Microsoft Graph API（この API に依存しているサービスは影響を受けている可能性があります）
・Office for the web（Microsoft Word へのアクセスに関する問題）
・SharePoint Online（Microsoft Word へのアクセスに関する問題）
・Project Online（アクセスできない）
・PowerPlatform および PowerAutomate（データベースを含む環境の作成ができない）
・Microsoft Managed Desktop 内の Autopatches
・Yammer（Yammer の実験への影響）
・Windows 365（クラウド PC のプロビジョニングができない）

現在は、最初のサービス復旧後に影響する事例は確認されておらず、引き続き、米国内の営業時間内において、サービスの監視を行い、問題の解消を確認するとのことです。

最近のグローバル管理データベースの導入が、本事象発生時に実行されていたサービスインスタンスと互換性がありませんでした。

このため、Enterprise Configuration Service（ECS）がサービス要求に対して空の応答を返したことにより、一部の Microsoft 365 サービス側で構成のオーバーライドを失い、予期しないエラーメッセージやユーザーから報告された動作への影響が発生しました。

今後は同様の問題が発生しないように Microsoft 365 サービスを強化するためのサービス改善のための要因の特定する作業を行っています。

また、5 営業日以内に PIR（Post – Incident Report）を発行する予定です。

この問題は、上記の Microsoft 365 サービスのいずれかを利用しようとするユーザーに潜在的に影響を与える可能性があります。

Microsoft 365

Glossary

ECS – Enterprise Configuration Service

An internal central configuration repository that allows services to make dynamic changes across multiple services and features.

Additionally, ECS allows us to make changes at a much more targeted level, including specific configurations per tenant or even per user.

Overall summary

On Thursday, July 21, at 1:05 AM UTC, we began receiving reports that users were unable to access or leverage features within the Microsoft Teams service.

We determined this outage was due to a failure in the enterprise configuration service that manages product configuration changes.

Unfortunately, a recent code defect created an incompatible configuration which was not handled properly by downstream services.

This subsequently led to cascading failures and availability impact primarily affecting Microsoft Teams.

We began our mitigation efforts by redirecting traffic to compatible instances at 2:40 AM UTC, and completed this effort at 3:45 AM UTC.

Once complete, many services recovered automatically, however, to expedite recovery we were required to make targeted service side restarts.

Additionally, some users may have needed to restart their Teams client to reconnect.

The majority of impact was recovered by 6:00 AM UTC; however, some users may have continued to experience residual impact with a subset of features until approximately 1:14 PM UTC.

This issue impacted all downstream services that leverage ECS.

The extent of the impact depended on how the service clients behaved when they encountered the issue.

This ranged from services crashing to services that had limited impact.

User Impact

Users may have been unable to use multiple Microsoft 365 services or features.

Microsoft Teams

The majority of impact occurred to the Microsoft Teams service based on how it consumes ECS updates.

This issue affected the users’ ability to connect to the Microsoft Teams Desktop, Web and Mobile clients.

Users who were able to login may have experienced issues with Teams’ features.

PSTN services

Users may have been unable to make calls during the service outage.

Additionally, this impacted services which depended on PTSN calling including; Azure Communication Service (ACS), Direct Routing, Managed Carriers, Skype for Consumer and Operator Connect.

Additionally, services such as Skype MFA, Audio Conferencing, P2P, Call queues. Auto attendant and Emergency calling were also impacted in both directions.

Telemetry indicated that approximately 300k calls were impacted by this event.

The Asia Pacific (APAC) region was most affected due to business hours coinciding with the impact window.

Additionally, Direct Routing and Skype MFA were mostly impacted service.

Other services

Additional Microsoft 365 services and features which experienced some impact included :

– Exchange Online (Delays sending mail)
– Microsoft 365 admin center (Inability to access)
– Microsoft Word within multiple services (Inability to load)
– Microsoft Forms (Inability to use via Teams)
– Microsoft Graph API (Any service relying on this API may have been affected)
– Office Online (Microsoft Word access issues)
– SharePoint Online (Microsoft Word access issues)
– Project Online (Inability to access)
– PowerPlatform and PowerAutomate (Inability to create an environment with a database)
– Autopatches within Microsoft Managed Desktop
– Yammer (Impact to Yammer flighting)
– Windows 365 (Unable to provision Cloud PCs)

Scope of Impact

This issue may have affected any user attempting to utilize the listed Microsoft 365 services.

Incident Start Date and Time

Thursday, July 21, 2022, at 1:05 AM UTC

Incident End Date and Time

The majority of impact was remediated by Thursday, July 21, 2022, at 6:00 AM UTC

There was some isolated residual impact which had recovered by Thursday, July 21, 2022, at 1:14 PM UTC

Preliminary Root Cause

A deployment in the ECS service contained a code defect that affected backward compatibility with services that leverage ECS.

The net result was that for services that utilize ECS it would return incorrect configurations to all its partners.

This resulted in downstream services getting a “200” status message (indicating the pull was successful), however, it actually contained a malformed JSON object.

The extent of the impact depended on how individual Microsoft services utilize the malformed configuration provided by ECS.

Impact ranged from services crashing such as Teams while other services experienced limited to no impact.

Actions Taken (All times UTC)

Thursday, July 21

・12:55 AM – The impact change was deployed to the ECS service.

Next Steps

Findings

Action

Completion Date

A change to ECS caused the underlying issue.

We’ve corrected the change which caused the incompatibility within the ECS service.

Complete

Our database and service update is packaged by design.

We’ve implemented a framework change to separate these updates.

Complete

The database and service changes being separated need to have sufficient Safe Deployment Time.

We’ve implemented a process change to ensure that database and service changes will be separated by 7 days.

Complete

Monitoring within the Pre-production environment was not tuned to detect this issue early in the deployment cycle.

We’re updating our monitoring thresholds to better identify this type of low-grade failure.

August 2022

The Microsoft Teams service does not fall back to a local version of ECS configurations in the event of an ECS failure.

We’re improving the resiliency of the Microsoft Teams service to fail back to a cached version

August 2022

The ECS service incorrectly returned a ‘200’ status message, which is considered valid.

We’re updating the error logic so that the service returns a ‘500’ error.

August 2022

Fault isolation did not sufficiently protect ECS from this failure.

We’re investing in further fault isolation to limit impact.
