Suboptimal routing for a subset of prefixes from ZRH

타임라인

   Routing is back to normal from every probe location. Duration: 41 minutes. Latency on the affected path was up to 25 ms above normal; no connectivity was lost.

   The leaked route has been withdrawn. We are keeping our more specific announcement in place for 13 minutes as a guard.

   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 Init7 to filter the leak upstream.

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