is GHC developers wiki down?

[Valery V. Vorotyntsev]

Clicking ``Developers (Wiki)'' link [http://hackage.haskell.org/trac/ghc]
from GHC page [http://www.haskell.org/ghc/] returns

    Environment not found

Neither the link is accessible from command line:

    $ curl -I 'http://hackage.haskell.org/trac/ghc'
