ADS Unavalable on April 13, 2017

The main ADS site at the Harvard-Smithsonian Center for Astrophysics (CfA), http://adsabs.harvard.edu, will be shutdown on April 13 at 4pm EDT and will remain unavailable till approximately 11pm due to scheduled maintenance of the local power supply line.

During this time, you can still access the ADS Classic interface on one of our mirror sites: http://cdsads.u-strasbg.fr/mirrors.html. The myADS notification service will be unavailable for the duration of the downtime.

The ADS Bumblebee interface will remain available, although some of its link-out and export functionality will be limited. Please feel free to use one of the available Bumblebee search forms:

The downtime will also affect the SIMBAD and VizieR mirrors at the CfA: http://simbad.harvard.edu/ and http://vizier.cfa.harvard.edu/.
