Following major building renovation work at the European Space Astronomy Centre (ESAC), we will be moving our data centre containing all our IT hardware infrastructure. We understand the inconvenience this may cause and sincerely apologize for this downtime. We’ve taken this opportunity to improve our data centre infrastructure to significantly increase its reliability and its energy efficiency. Our teams will be working hard to resume all our services as soon as possible, once the move is complete.
