Echo Server Down

Resolved

Resolved Feb 22, 2022 at 12:08am UTC

Why this happened

We switched to a new server cluster during the Echo server maintenance conducted on February 20. We had prepared the servers based on the past load, but the load balancer that distributes requests to the servers could not withstand the load and could not accept some requests.
In this recovery work, we reverted to the old cluster.

How to prevent this in the future

We will enhance the load balancer's performance so that it can withstand the expected number of reque...

Error might occur due to the instability of the server

Resolved

As a result of automatically increasing or decreasing the number of servers depending on the load, there were cases where reboots were triggered under certain conditions. When this happened, meetings were disconnected or people were forced to leave the space.
We have fixed the problem so that the reboot process will not run under certain conditions.
We apologize for the inconvenience caused over a long period of time.

Realtime reflection is not working on all workspaces

Resolved

Resolved Dec 1, 2021 at 9:41pm UTC

English Below

障害内容

16:38から21:41の間、リアルタイム処理を行なっているサーバーが高負荷により停止し、以下の機能が利用不可能となっておりました。
・会議室への入退出
・アイコンの右上の絵文字の変更
・ワークスペースのレイアウト変更

原因

リアルタイム処理を担っているサーバーの1台にアクセスが集中し、1つのサーバーが停止しました。その後ユーザから一斉に再接続のリクエストが走ったため、残りのサーバー群に対してもアクセスが集中し、リアルタイム処理を担っていたサーバーがすべて停止しました。
すぐに再起動を試みましたが、再接続のリクエストが短い時間間隔で送られてくることにより、再起動後すぐにサーバーが高負荷状態となってしまい、復旧に時間がかかっておりました。

対策

・一部のサーバーが停止しても、連鎖的に全てのサーバーがダウンすることを防ぐため、サーバーを増強しました。
・非効率な処理方法により、容易に高負荷を引き起こしやすい状態となっていたため、そのロジックを修正する予定です。
