• we are trying to collect information about upcoming Fermi computing outages (disks, oracle, network) to improve planning
• when planning an outage, please send an email to datalist and write the description here (including requested duration and preferred timeframe)
• we will try to combine outages as much as possible, in order to maximize uptime for time-critical services (FASTCopy, pipeline, etc.)
• once the plan is finalized, don't forget to send a message to glast-outage and the collaboration (if applicable)
