Dear users,

due to a long planned power outage, this system will be unavailable from

Friday, 11th of November 6 am CET


Monday, 14th of November 12 am CET

(If things go well, we might be back late in the evening of Sunday, 13th of November - so you might give it a quick try, if you have urgent stuff to do here)

See you on Monday,

Jan Sellmann for Central IT Services of the Max Planck Institute for Meteorology
