Having checked with Jeroen, I would like to observe that in the case  
of APNIC this is almost certainly IPv6 and pMTU problems.

As he observes elsewhere in the email, we all shadow each others data  
in the FTP trees so you can very probably choose one RIR, and use it  
as a fetch-point for all of this data.

BTW The last time this cropped up in any public eye facing NANOG type  
people it was the rfc editor. It can happen to anyone. Geoff wrote it  
up at:

So, this is not APNIC having "broken" FTP, its the innate problem of  
IPv6 in the wild.

If you fall back to V4, the fetch works just fine. If tomorrow you  
have problems fetching the stats from ARIN or RIPE, you might want to  
look at your path..
