Degraded Performance – Sky Stream NOTAMs Feed (AWS US‑East‑1)

Incident Report for Cirium

Investigating

We are currently investigating reports of degraded performance affecting the Sky Stream NOTAMs feed, which appears to be related to an AWS service disruption in the US‑East‑1 region. As a result, some customers may notice a reduction in message frequency on the NOTAMs feed. As a precaution, we are also reviewing other Cirium services to assess whether they may be impacted by the same AWS disruption. Our teams are actively monitoring the situation and continuing to investigate. Further updates will be shared as more information becomes available. Thank you for your patience and understanding.
