Anunna is taken down for planned maintenance — firmware and software updates — roughly twice a year. Typically one downtime is scheduled in April or May, in a week free of teaching, and another in October, to disrupt usage as little as possible.

During a downtime the cluster is unavailable. Jobs are not scheduled to run across a planned downtime, so check the announced dates when planning long jobs.
