Anunna maintenance
Anunna is taken down for planned maintenance — firmware and software updates — roughly twice a year. Typically one downtime is scheduled in April or May and another in October, in a week free of teaching, 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.
Announcements
Planned maintenance is announced in advance — watch the Message of the Day on the Apps Portal, login nodes and we always send out an announcement in advance over e-mail.
Reporting problems
If something is not working — during or outside maintenance — see How to Get Help.
