Anomalies:

- 01/13/2016 - SOAR S-ACE-91 - Network problem affecting ACE_DATA_FWD and
Email notification delay.

Network problems at the start of the D-15 pass on DOY 13 became apparent,
causing early connection attempts to NOAA and Caltech to fail. The
connections were successful during the 15:43 - 15:47 (UT) time window. In
addition, a delay in notification emails was observed, which persisted
throughout the day. Note that there was no scheduled network maintenance
work during the D-15 contact time.

Impact:

Minimal - Delay of automated operations-related notification emails.  NOAA
and Caltech did not received forwarded data during the outage (from
approximately 15:20 UT through 15:47 UT).


- 01/13/2016 - SOAR S-ACE-92 - DSN MDS1 (Monitor Data Server) Failure (DR#
G116882)

Loss of monitor and ranging data due to a DSN MDS1 (Monitor Data
Server) failure. DSN reported downtime from 16:57 to 18:11 UT (74 minutes
total;  Ref: DSN DR# G116882). As a result of this failure, a problem on
the SLE command connection occurred at 17:07 (UT).  The SLE connection was
restored at 17:51 (UT), as verified at the MMOC.

Impact:

Minimal - No DSN monitor data available to the FOT during the
16:57 (UT) ¡© 18:11 (UT) time frame, and no commanding/forward link
during the 17:07 (UT ) - 17:51 (UT) time window (but ultimately, with no
impact to achieving the planned contact commanding goals).
