CDS services downtime

[Thomas Boch]

Hi Petr,

First, I agree Sesame is a critical piece for many services and tools, 
and we consider it as such at CDS.

As explained in the Sesame documentation page ( 
http://cdsweb.u-strasbg.fr/doc/sesame.htx ), there is a Sesame mirror at 
CfA, its base URL is http://vizier.cfa.harvard.edu/viz-bin/nph-sesame
I tried it today around 11am GMT, and it was working fine as far as I 
can tell.

Several tools, including Aladin Desktop and Astropy coordinates package, 
are taking advantage of the existence of the mirror as a fallback in 
case the main Strasbourg service does not reply.

Thomas
