Data missing |

For the past couple of days, the summary pages have shown minute trend data disappear at 12:00 UTC (05:00 AM local time). This seems to be the case for all channels that we plot, see e.g. https://nodus.ligo.caltech.edu:30889/detcharsummary/day/20150724/ioo/. Using Dataviewer, Koji has checked that indeed the frames seem to have disappeared from disk. The data come back at 24 UTC (5pm local). Any ideas why this might be?

Possible explanations:
- The data transfers to LDAS had been shut off while we were doing the DAQ debugging. I don't know if they have been turned back on. Unlikely this is the problem since you would probably see no data at all if this were the case.
- wiper script parameters might have been changed to store less of the trend data for some reason.
- Frame size is different and therefore wiper script parameters need to be adjusted.
- Steve deleted it all.
