I've been trying it throughout today and it works about 10% of the time. 
  This is on a long sequence - 7kb; it always works on the 3kb examples 
I need and shorter. It also works fine when querying the 7kb against the 
ecoli database.

Still, it sounds like the 404 problems may not be down to biopython. Do 
you think it's worth contacting NCBI directly?
