 hackage-mirror against hackage.haskell.org fails with,

 While the source of the error is unclear, it's a sign that the error
 handling should be more robust. Perhaps failing packages should be skipped
 until it's very clear that something is horribly wrong (e.g. a heuristic
 like 10 packages fail in a row)?
