problem with www.sugarlabs.org and sugarlabs.org not same site

[Sean DALY]

David - I'm sorry I need to ping you on this but we will have more
(possibly much more) traffic on Monday and anyone typing in
http://sugarlabs.org will never see the new site at
http://www.sugarlabs.org :-(

And, anyone arriving on the new site and clicking through to the wiki
has no navigation to return except multiple back-button presses on the
browser - clicking on the wiki logo links to http://sugarlabs.org,
without the dub-dub-dub

Could it be a CNAME issue?

thanks

Sean
