apt-get-update missing files errors

[Bob]

When running sudo apt-get update on Precise and Trusty, the process times out. I ran sudo strace apt-get update and that provided possibly useful feedback:

read(6, "400 URI Failure\nURI: http://down"..., 64000) = 157
stat("/var/lib/apt/lists/downloads-distro.mongodb.org_repo_debian-sysvinit_dists_dist_10gen_i18n_Translation-en%5fUS", 0x7fff46829e00) = -1 ENOENT (No such file or directory)

read(6, "400 URI Failure\nURI: http://down"..., 64000) = 173
stat("/var/lib/apt/lists/downloads-distro.mongodb.org_repo_debian-sysvinit_dists_dist_10gen_i18n_Translation-en", 0x7fff4682a120) = -1 ENOENT (No such file or directory)

stat("/var/lib/apt/lists/downloads-distro.mongodb.org_repo_debian-sysvinit_dists_dist_10gen_i18n_Translation-en%5fUS", 0x7fff4682a120) = -1 ENOENT (No such file or directory)

stat("/var/lib/apt/lists/downloads-distro.mongodb.org_repo_debian-sysvinit_dists_dist_10gen_i18n_Translation-en", 0x7fff4682a120) = -1 ENOENT (No such file or directory)

I tried navigating to the relevant url, and it seems that the files and the expected directory structure are not there:

http://downloads-distro.mongodb.org/repo/debian-sysvinit/dists/dist/10gen/

This appears to be related to mongodb.

This doesn't appear to be a network issue and it has been ongoing since Thursday (I'm reporting the bug on Monday)

Add that this is happening in both Trusty and Precise.
