Hiya, Tomorrow the plan is to install a new disk drive in thelma, the expected down time will be about 10-30 minutes. This will happen at 16:00 UTC (thurs). I wouldn't fail over to iita unless one doesn't get data for 30 minutes. The fail over scheme is: thelma -> iita.rap.ucar.edu -> noaaport.ssec.wisc.edu -> nport.alden.com Thanks, Robb... =============================================================================== Robb Kambic Unidata Program Center Software Engineer III Univ.
