OSCER Users,
Schooner maintenance has now completed. Some of the compute nodes are still
being diagnosed. If you own a condominium compute node, and need an update
of when your node will be back online, please send us an email and we'll
give you a status update. In general, the estimate is going to be, by the
end of the day tomorrow (Wed Nov 27th 2024).

Thanks,
Dave
