Hi Michael,

Sites often ingest the same data from two sites for redundancy..in case one LDM 
goes down, you will not need to do anything :) The LDM is "smart" enough not to 
request duplicates (using an MD5 checksum).

fyi..the "PRIMARY" semantic is no longer needed, it can be removed.

We have made a name change on the NSF machine:
idd.geo.nsf.gov

that alias may still work, but will go away, the new name is:

idd.cise-nsf.gov

and you can still use our machine:

idd.unidata.ucar.edu

..as a secondary, failover feed.

I will place you as the point of contact for McGill, please let us know if you 
encounter any problems.

Cheers,

Jeff
