A major upgrade of all electrical systems at the Strasbourg Observatory will result in a complete power outage scheduled on Monday, April 3, 2017, starting at 07:00 CET (5:00 a.m. GMT), and lasting 6 to 10 hours.

As a consequence, all CDS services located in Strasbourg will be shut down during this time. You are strongly encouraged to use existing mirrors, such as Simbad at CfA, or VizieR at CfA, Tokyo, CADC, IUCAA in India, Beijing Obs., or SAAO in South Africa.
