If there are DSN problems, then data loss (1-10 hours) may occur. The DSN schedule is changing, so opportunities to acquire more time may be possible. DSN has upgraded the SLE software (v33.4 to v34.1) on their telemetry servers. (Space Link Extension is the protocol for data between the MMOC and DSN.) DSN transitioned ACE from the SLE4 server (old software) to SLE3 server (new software) on Tuesday 06/24/2014. No problems have been found. Note, DSN is continually improving and upgrading software; changes are included in this weekly report only when problems occur or the FOT is notified of the changes. ======================================================================== Anomalies: None
