Usually compression is provided by the webserver=
, but maybe ours 
is not configured to do that.  I think we're the o=
nly distro to 
provide compressed isos.

Really?  Mos=
t distribution ISOs use squashfs or similar with 
XZ/LZMA compression.  =
It doesn't make sense to compress that over 
the wire.

That s=
aid: XZ compression currently saves 27% (559M -> 405M). 
Transparentl=
y serving pre-compressed ISOs with nginx (gzip level 
9) would save abou=
t 25% (559M -> 415M), which is surprisingly 
similar.
