Comment (by wfn):

 95.85.10.71 does indeed return a `503` (should have seen this myself,
 whoops.) Upped the limit, and at least the compressed descriptors archive
 is now being returned.

 Its `.z` returned is successfully parsed by python's `import zlib; print
 len(zlib.decompress(open('all.z', 'rb').read()))`, ''and'' the archive
 ends with a different four byte tail (seems unique etc., assuming it's the
 adler32 checksum.) Re-downloaded later, another different tail.

 (Re: other things that Nick said, will try and see to them, but won't
 happen before ~tomorrow)
