Elevated latency to the Gulf states from AMS

   Latency to the Gulf states is back to its usual level. Duration: 1 h 14 min. Throughput was not affected; only the round trip on that path was.

2. 观察中2025年5月27日 03:15 UTC

   The direct peering route has been re-announced. We have removed our preference and are watching latency settle.

   A peer on AMS-IX has withdrawn its direct route to the Gulf states and traffic is taking a detour via Lumen. This is a routing choice on their side, not a fault on ours. We have preferred Arelion for those prefixes, which brings the round trip back within 10 ms of normal.

   Round-trip times from AMS to the Gulf states are 29 ms above their usual level. The path goes over AMS-IX; nothing has changed on our side. We are checking whether a peer has moved traffic onto a longer path.
