Dear all,

as anticipated, GRAS data products have become unavailable at 07:00 UTC
due to the outage of GSN auxiliary data.

In the meantime, our colleagues at ESOC have worked hard and were able 
to successfully restore their service. Operational GRAS processing has 
started again, with data being available after 08:57 UTC. Please note 
that the Precise Orbit Determination process requires some time to 
converge to nominal quality; GRAS level 1b data will therefore remain 
flagged as containing degraded bending angle data for another 4 hours, 
i.e. until 13:00 UTC.

We apologize for the inconvenience the outage may have caused on your 
side.

With kind regards,

 Christian.
