Nikon France website is currently down and has been down for a while. Updates for next week maybe? If you have followed NR in the past you probably know that there is a certain pattern before an official announcement and bringing the website down for maintenance is part of it (it is beyond me why they cannot do this without bringing the site down).
UPDATE: Here are some examples of Nikon websites being down shortly before an official announcement:
Of course there are some cases where Nikon sites ware down because of technical issues (I have a record of only one) and one case where the outage was announced in advance.
