thelma.ucar.edu went down when the NCAR Mesa lab lost power yesterday
evening.  We pressed a spare at Unidata into service as a 'new' thelma,
but this machine was unable to keep up with the ingest and relay load
that the original thelma carries (the new machines is a Sunfire 280R;
thelma is a Sunfire 480R).  I took the liberty of logging onto user
machines that I had access to and switching their feed requests from
thelma to emo.  I thought that I verified that the sites I switched
were getting data, but I obviously didn't check closeley enough to make
sure that rainbow.al.noaa.gov was receiving data.  I apologize for
this.

>How can I resolve it???

I just added a global allow for .gov sites in emo's ldmd.conf file and
stopped and restarted the LDM.  If you left the requests to emo on
rainbow, it would resume getting data now.  I see, however, that you
switched back to thelma this morning; this is OK now that the
load has been lessened on the replacement thelma.

I apologize for not being more diligent in making sure that data
was flowing from emo to rainbow.  It was a long night...
