The NOAA network is gradually being restored.  MHS data appears to have started flowing around 02:00 UTC on 23 October 2014, but as of 08:00 UTC on 23 October 2014 the Meteosat geo-IR data was still  missing.  As a result, users should see reduced areas of "missing" and higher-quality estimates in general starting with the 03:00 UTC 23 October 2014 3B42RT.
