The host is running pacredir [0][1], which listens on localhost and redirects
to hosts it found on local network. But pacredir returning 404 is a valid
answer, it just means the file is not available in local network. In this
case pacman just uses the next mirror.

In fact pacredir is accessible form client, but things would break
as it has just this single server configured. There is no fallback to a real
mirror that has all the files required.
