ARC Maintenance Outages
ARC systems will be taken offline regularly to perform essential maintenance tasks which are unreasonable to perform during normal operations. During these outages, the systems will be inaccessible to researchers and students and jobs will not run.
Regular Cycle
Starting in 2023, ARC established an annual senquence of maintenance outages at regular intervals to help make these service interruptions more predictable. Each year there will be three planned maintenance outages. The exact dates will vary from year to year but follow this pattern:
