【トラブルシューティング】投稿やコメント、メッセージが期待通りに表示されずフィードが読み込まれない場合がある SI（サービス インシデント）が発生！【YA314035】【PIR】【復旧済み】

が提供する Microsoft 365 のサービス正常性（YA314035）にて、Yammer への投稿やコメント、メッセージが期待通りに表示されずフィードが読み込まれない場合がある SI（サービス インシデント）が発生していることを発表しています。

現在は影響していたシナリオへの対処が完了しており、広範なテストの結果、この問題が完全に解決していることを確認しているとのことです。

• ・新規投稿の閲覧が行えない
• ・Yammer のフィードの読み込みが行えない
• ・メッセージが表示されず、”Your message was successfully posted but isn’t displaying right now. You can refresh in a few minutes to see it.” というエラー メッセージが表示される
• ・SI（サービス インシデント）発生中に送信されるはずの通知が送信されない

なお、この問題の解決後もごく一部のユーザーにて以下の影響が残っている可能性もあります。

• ・SI（サービス インシデント）発生により、固定されていた一部の投稿の固定が解除解除されている可能性があります。
• ・回答済みの質問が未回答のフィードに表示されることがあります。
• ※ “ベスト アンサー” はハイライトされたままになります。
• ・SI（サービス インシデント）発生中にコミュニティーからコミュニティーへスレッドを移動すると両方のコミュニティーでスレッドが重複して表示されることがあります。

ただし、上記に記載されているシナリオにおいては引き続き影響が残っている可能性があるため、影響緩和に関する最新のスケジュールは今週末に発表される予定とのことです。

この問題は Azure データベース パーティションの一部で可用性の状態が安定しないことにより、最適なレベル以下で動作したことから本事象に影響し発生していたとのことです。

現在は、可用性の問題とその後のサービスへの影響への根本的な原因を特定するために追加で調査を行っており、近日中に発行予定の事後報告書にて発表されるとのことです。

なお、5 営業日以内に PIR（Post – Incident Report）が公開されます。

※ 本事象は該当するインフラストラクチャーを経由しているすべてのユーザーにて影響を受けている可能性があるとのことです。

また、最初の問題の解決後も一部のユーザーには影響が残っている可能性があります。

Post Incident Repot（PIR）

Incident Information

User Impact

Newly created Yammer posts, comments, and messages weren’t delivered to other users as expected.

• ・Additionally :
• – Messages were not displaying as expected and users would have noticed this error message :
• “Your message was successfully posted but isn’t displaying right now. You could refresh in a few minutes to see it.”
• – Users had issues loading Yammer feeds in approximately 3% of cases.
• – Notifications that should have been sent during the affected outage were not sent.

After the core issue was resolved, a very small number of users may have still experienced the following residual impact scenarios :

• – Some posts that were pinned during the impact may have become unpinned.
• – Answered questions may have appeared in the unanswered feed; however, the “best answer” would have remained highlighted.
• – Moving thread from community to community during the outage window would have caused the thread to appear in both communities.

Scope of Impact

Any user routed through the affected infrastructure in the North America region may have been affected.

Once the initial service issue was resolved, a small subset of users may have continued to experience some residual impact as described above.

Customers served through infrastructure hosted in the EMEA region were unaffected.

Incident Start Date and Time

Thursday, January 13, 2022, at 3:56 AM UTC

Incident End Date and Time

Friday, January 14, 2022, at 9:26 AM UTC

Root Cause

A portion of Yammer’s database shards entered a degraded state.

As such, the remaining shards were unable to process new requests, thereby preventing message delivery to Yammer feeds and inboxes.

Actions Taken (All times UTC)

Thursday, January 13

• ・4:06 AM – We received reports from telemetry that indicated message delivery delays within Yammer.
• We started to analyze analytics to understand the cause and develop a fix.
• ・4:22 AM – We determined that customers would see the message “Your message was successfully posted but isn’t displaying right now. You can refresh in a few minutes to see it.”
• However, users would have been able to read their feeds and create messages.
• We continued our efforts to analyze logs.
• ・5:01 AM – We discovered that the affected functionality is dependent on an internal database system which wasn’t responding to the service as expected.
• ・6:15 AM – We investigated analytics from the service and the diagnostics from the database system to identify the root cause.
• ・10:33 AM – We determined that some shards were unavailable, indicating that we would need to start a database restore from a snapshot backup taken several hours prior to the incident.
• ・11:18 AM – We initiated the recovery of the affected shards from a previous backup.
• We estimated that the database restore would take between 5-10 hours.
• ・11:45 AM – While waiting for database restore to complete, users continued to post new messages, but messages sent after the timestamp of the restore would need to be re-applied.
• We began analyzing and planning for the reingestion process of messages delivered after the time of database restore snapshot.
• ・5:05 PM – The database restore completed, and we began the process of re-applying message actions and deletes that were affected during the impact window.
• We designed, coded, and deployed service changes to replay events currently in this state.
• ・10:19 PM – There were multiple event streams for various Yammer message types and user actions, and due to the complex nature of reingestion of these activities, it took an extended amount of time to develop, test, and verify the results.
• We took additional precautions during this time, to ensure that the overall system would arrive at a consistent state.

Friday, January 14

• ・1:35 AM – We made additional configuration changes to the database prior to restoration.
• After the configuration changes were applied and the new database was brought online, feed loading errors as described in the user impact section recovered.
• While affected feeds started loading correctly, the latest messages weren’t appearing yet.
• ・3:02 AM – We began re-applying impacted messages and actions in a specific order, to ensure overall system consistency.
• While this re-delivery process was underway, users would continue to see message delays.
• ・9:26 AM The backlog of delayed message delivery and delete events was fully processed, and message events caught up to “real time”.
• As such, Yammer’s core features of message posting, message delivery, and feed loading were restored at this time.
• ・9:40 AM Based on telemetry and customer reports, we investigated additional notification related delays and confirmed a large queue of delayed notifications had built up.
• Because notifications are time-sensitive, we dropped the backlog of notifications in the queue, thus restoring current “real time” notifications to normal operation.
• ・7:15 PM – We validated service health across all features. During this process we identified additional impact scenarios for approximately three percent of cases, which were listed in the Service Health Dashboard (SHD) notification.
• We began our efforts to fix the residual issues.
• ・10:00 PM – We developed an action plan to address the residual impact.
• Which included but were not limited to configuration changes and checks to existing functionalities

Thursday, January 20

• ・1:13 AM – We validated that all residual impact referenced in the user impact statement above were fully resolved.

Next Steps

• ・More info :
• – Users were unable to see new posts being created.
• – Users had issues loading Yammer feeds.
• – Messages were not displaying as expected and would have noticed this error message :
• “Your message was successfully posted but isn’t displaying right now. You could refresh in a few minutes to see it.”

• ・After this issue was resolved, a very small number of users may have still experienced the following residual impact scenarios :
• – Some posts that were pinned during the impact may have become unpinned.
• – Answered questions may have appeared in the unanswered feed; however, the “best answer” would have still remained highlighted.
• – Moving thread from community to community during the outage window would have caused the thread to be duplicated in both communities.
• ・Scope of impact : Any user routed through the affected infrastructure may have been affected.
• Once the initial service issue was resolved, a small subset of users may have continued to experience some residual impact.
• ・Start time : Thursday, January 13, 2022, 12:56 PM (3:56 AM UTC)
• ・End time : Saturday, January 15, 2022, 6:26 AM (1/14/2022, 9:26 PM UTC)
• ・Preliminary root cause : A portion of Azure database partitions were in an inconsistent state of availability, causing the remaining partitions to operate at sub-optimal levels and resulting in impact.
• Next steps :
• – We’re performing an additional investigation to determine the underlying cause of the availability issues and subsequent service impact.
• – Additional action items will be provided in the forthcoming post-incident report.
