Dataset1001, the host which serves dumps and other datasets to the public,
as well as providing access to various datasets directly on stats100x, will
be unavailable tomorrow for an upgrade to jessie. While I don't expect to
need nearly 3 hours for the upgrade, better safe than sorry. In the
meantime all files will be accessible via
ms1001.wikimedia.org via the web,
and all dumps and page view files from our mirrors as well.
Thanks for your understanding.
