Alerts and notices occur when there are outages to our system. Outages can be as simple as short network outages, where we will have a brief pause in operations, to larger power events requiring outside support. Not all events result in data loss, and any outage resulting in data loss is manually annotated by the ONC Data Team.
This page shows current and past outages and major incidents for the main ONC observatories. It does not include specific instruments or infrastructure components. The timeline bar colours on this page indicate current performance, with green indicating Operational, yellow indicating Degraded Performance, or Partial Outage and red for indicating Major Outage.
