Gandi.net Groups

I registered, with forwarding mainly to users.skynet.be, a few domain
names. Among them, I added two names last Thursday, both forwarded to
the same skynet user and folder, in the format 

domain-name.be 
and
www.domain-name.be

Quite immediately, I was able to access these two domains when connected
to internet through my skynet account. But other people had no access
yet. I saw that when pinging these names, the previously existing ones
were routed through "webredir.vip.gandi.net" while the two new ones
routed directly to "domain-name.be". 

As of Monday this week, "www.domain-name.be" is also routed via
"webredir..."  but "domain-name.be" is still direct. 

(All forwardings are set as "masked"). 

I tend to believe that users which are not on the Skynet ISP can only
access the names through "webredir". Is that true? 

What do I need to do to have the name w/o subdomain working? Yesterday I
suspected it wasn't possible to have both names directed to the same
folder, so that I changed one. But this does not seem to have an effect
and I restored the common forwarding. 

Thanks for your supportl
