Just wanted to sound the alarm on this one in case it needs attention:

 $ mix local.hex --force
** (Mix) httpc request failed with: {:bad_status_code, 500}

Could not install Hex because Mix could not download metadata at https://builds.hex.pm/installs/hex-1.x.csv.

Alternatively, you can compile and install Hex directly with this command:

    $ mix archive.install github hexpm/hex branch latest

EDIT: I think the build server is indeed having some issues. Navigating to https://builds.hex.pm/ in my browser also returns only the ominous Internal Server Error message.

EDIT 2: Is there a better place to report stuff like this?

EDIT 3: I looked in the Elixir Slack, the issue will be resolved shortly.

EDIT 4: Everything is back to normal now. What a ride!
