Comment (by duncan):

 Note that it is using a proxy server, that's what these two lines are
 about:
 {{{
 X-Cache: MISS from mds-swf1.mds.aw.loc
 Via: 1.0 mds-swf1.mds.aw.loc:8080 (http_scan/4.0.2.6.19)
 }}}
 It is however a transparent proxy, ie cabal itself is trying to connect
 directly to `hackage.haskell.org` but your network setup transparently
 redirects that to `mds-swf1.mds.aw.loc:8080` which is an http proxy.
