タイムライン

1. 解決済み2025/05/22 23:26 UTC

   The GlobalConnect uplink in STO has been clean for 5 minutes with the session restored. Total duration of the degradation: 42 minutes. No machine lost connectivity; some traffic saw higher latency during the detour.

   GlobalConnect reports the card replaced. We have re-enabled the session and are watching error counters before calling this resolved.

   GlobalConnect has confirmed a faulty line card on their side of the STO handover. We have withdrawn our prefixes from that session, and all traffic is leaving through Arelion and Netnod for now. Loss has cleared; latency to some destinations is 3–6 ms higher while the detour is in place.

4. 調査中2025/05/22 22:50 UTC

   We are investigating packet loss of around 5% towards a subset of destinations from STO. Alerts fired at 22:44 UTC on the GlobalConnect uplink; the Arelion uplink and the Netnod peering are clean. Machines remain reachable.
