We currently experience some technical difficulties in our computer room. Some of our services (including SIMBAD, Sesame, the CDS portal) are not available. We do our best to go back to normal state ASAP.

We would like to remind you that some of the CDS services are mirrored and can be used as an alternative when the main site is not working :

• SIMBAD mirror at CfA: simbad.harvard.edu/Simbad

• Sesame mirror: vizier.cfa.harvard.edu/viz-bin/Sesame

• VizieR mirrors:

• VizieR at ADAC

• VizieR at CADC

• VizieR at Cambridge

• VizieR at INASAN

• VizieR at Beijing Obs

• VizieR at CFA Harvard

• VizieR at JAC
