[API-users] Downloading large numbers of datasets

Hi Clint,

You're first to report a problem, though trying to download the file 
(64-bit Linux, wget) within the GBIF network also failed for me.

I've copied it with a different method to here: 
http://download.gbif.org/2016/12/0039949-160910150852091.zip -- on a 
plain Apache server, so wget's "--continue" option should work if necessary.

The MD5 checksum is e976523c9e6c7ec0cd9d3cb30030020b and the size is 
exactly 43,184,530,448 bytes.

If downloading that doesn't work, I could split the file into chunks.  
We'll also look into why the download failed [1].
