Unable to download ancillary data

Hi, I'm downloading data from your servers in order to produce daily compositions but today I found that my IP seems to be blocked. Do I have to use bandwidth limitation? Or what are the good practices?

I can access https://oceancolor.gsfc.nasa.gov/ from my computer but not from my server.

Thanks.
