I suspect that the "is not a bzip2 file" indicates something is actually
wrong in a proxy on your way to that host or on that host itself.

I wrote a bash program lp:~smoser/+junk/check-archive to check archives
for this purpose a while a go.  I run it on de.archive.ubuntu.com here and
it seems fine:

$ ./check-archive -vvv http://de.archive.ubuntu.com/ubuntu \
     precise precise-updates precise-proposed precise-backports

That doesn't mean that the server was not actually broken when you
reported this, nor does it mean there is nothing in *your* path breaking
it.  It just means that from my IP to that mirror, it looks good.

I've actually never seen the '(stdin) is not a bzip2 file" errors before.
