[Dune] dune-project.org (conan) maintenance this afternoon

[Sven Marnach]

Hi,

this afternoon starting at 2 p.m., we will shut down the
dune-project.org server for maintenance.  Mailinglists, subversion
repositories and web page will be unavailable for a few hours.

We apologize for any inconveniences and try to keep the downtime as
short as possible.

Greetings,
    Sven
