Looks like the A records (the GLUE) got from the parent zone check are different than the ones got from your nameservers. You have to make sure your parent server has the same NS records for your zone as you do.I detected some problems as follows:
For ns2.myfriendsspace.com the parent reported: ['199.193.112.104'] and your nameservers reported: ['199.193.112.103']
For ns1.myfriendsspace.com the parent reported: ['199.193.112.104'] and your nameservers reported: ['199.193.112.103']
May be this is the reason some users are having problem.
Same here, still cannot access the site. It gives me a connection timed out error every time. I've tried it from FireFox & Chrome & I cleared all my cookies, cache, & history in my browser as well as flush my dns cache again on my laptop still nada.
