平成 29 年 8 月に発生した大規模な
インターネット接続障害に関する検証報告
平成 29 年 12 月
電気通信事故検証会議
（表１）経路情報の誤りによるインターネット障害の発生状況
発生年月 発生場所 発生事象
2017 年 11 月
米国、カナダ、
ブラジル、アル
ゼンチン、アラ
ブ首長国連邦
米国の Tier1 事業者である Level3 Communications が、本来配信する予定で
なかった数千もの詳細な経路情報を誤設定により契約事業者に配信したこと
により、米国大手 ISP である Comcast、カナダ大手 ISP である Bell Canada
や、大手コンテンツプロバイダである Netflix 宛ての通信が Level3
Communications を回り込むこととなり、Comcast や Bell Canada だけではな
く、ブラジル、アルゼンチン、アラブ首長国連邦の ISP に約 90 分のインター
ネットの遅延が発生。4
2015 年 6 月 マレーシア
マレーシアの ISP である Telekom Malaysia が、米国の Tier1 事業者である
Level3 Communications に約 17 万 9 千もの経路情報を配信したが、当該経路
情報は Telekom Malaysia を回り込む経路となってしまったため、世界中で約
2 時間インターネット接続の遅延が発生。5

2014 年 8 月 米国及びカナダ
の一部地域
大手 ISP のルータのグローバルルーティングテーブルに 15,000 件の新しい経
路情報が追加されたことにより、ルータのメモリ容量が不足し、ルータの処理
遅延が発生。
これにより、インターネット通信が不安定となり、一部のサイトが全く読み込
まれない事象が発生。6
2012 年 8 月 カナダ
カナダの ISP である Dery Telecom Inc が VIDEOTRON から配信された 10 万超
の AS パスの長い経路情報を Bell に配信し、Bell（あるいは Dery Telecom）
のフィルターが最適に稼働しなかったことにより、ピア接続しているインド
の Tata をはじめとする事業者にそのまま配信され、Bell や Tata のインター
ネット接続に障害が発生。7
2012 年 2 月 オーストラリア
オーストラリアの大手 ISP である Telstra とトランジット契約をしている
Dodo が、設定誤りにより Telstra への経路をインド経由する設定としてしま
い、約 30 分インターネットに接続しづらい状況が発生。8
2009 年 2 月 チェコ
チェコの ISP がルータのバグあるいは設定不良により、同じ AS 番号を多く連
結された不適切な AS Path を配信したことにより、一部の処理能力の低いル
ータが機能停止。
これにより、一部の ISP において約 1 時間インターネットが接続できなくな
った。（Long AS Path 事件）9
