I just restarted the primary and redundant GDS calibration pipelines at GPS time 1263067200.  The latency had already climbed to ~10s since yesterday, likely due to long data dropouts that normally occur during Tuesday maintenance.  Note, this problem should no longer occur when gstlal-calibration-1.2.12 is installed.  See LLO aLOG 50942 for details about the latency bug fixes.
