Server cannot reached in different locations. Who I should blame, domain registrar or hosting company?

My site is not reachable by 36 Host of 50 host all over the world: http://host-tracker.com/check_res_ajx/7999858-0/

Hosting company told me it’s the problem of DNS and Domain Registrar (My DNS Server is DNS-DIY Which is free service by OnlineNic) and Domain Registrar told me this is a problem of Hosting company (iWeb).

My primary domain is www.sanaram.com and my Nameservers are ns1.risaman.com=>184.107.58.109 and ns2.risaman.com=>184.107.61.137

Can you please tell me how can I understand where is the root of evil? I would appreciate any help.

this is certainly a registrar-problem and has nothing to do with your personal internet-access. If a site is inaccessible on more than your own location your domain is not yet propagated to every rootserver, contact your Domain registrar and show them the above link.

edit : http://www.sanaram.com/ works from here (Germany)
