   Routing is back to normal from every probe location. Duration: 16 minutes. Latency on the affected path was up to 17 ms above normal; no connectivity was lost.

   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.

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