Suboptimal routing for a subset of prefixes from STO

タイムライン

1. 解決済み2023/04/10 12:35 UTC

   Routing is back to normal from every probe location. Duration: 48 minutes. Latency on the affected path was up to 24 ms above normal; no connectivity was lost.

2. 監視中2023/04/10 12:28 UTC

   The leaked route has been withdrawn. We are keeping our more specific announcement in place for 7 minutes as a guard.

3. 原因特定2023/04/10 12:03 UTC

   A transit provider two hops away leaked a more specific route for one of our /24s. We have announced the same more specific ourselves so that it wins on the shortest path, and we have asked Arelion to filter the leak upstream.

4. 調査中2023/04/10 11:49 UTC

   A subset of our STO prefixes is being reached over an unusually long path from East Asia. We see it in our external probes; users in other regions are not affected.
