Question regarding to www.fedoraproject.org

Dear Sir,

My name is Keng Soon Goh, and I am working for Hughes Network Systems. We are Service Provider for satellite company, and one of our client was having problem accessing to your websites through IPv6 address. When I run DNS lookup, I noticed three IPv6 addresses as below.

nslookup -q=aaaa www.fedoraproject.org
Server: 172.27.0.9
Address: 172.27.0.9#53

Non-authoritative answer:
www.fedoraproject.org canonical name = wildcard.fedoraproject.org.
wildcard.fedoraproject.org has AAAA address 2001:4178:2:1269::fed2
wildcard.fedoraproject.org has AAAA address 2607:f188::dead:beef:cafe:fed1
wildcard.fedoraproject.org has AAAA address 2610:28:3090:3001:dead:beef:cafe:fed4

Authoritative answers can be found from:
fedoraproject.org nameserver = ns02.fedoraproject.org.
fedoraproject.org nameserver = ns04.fedoraproject.org.
fedoraproject.org nameserver = ns05.fedoraproject.org.
fedoraproject.org nameserver = ns-sb01.fedoraproject.org.

We noticed that one of your IPv6 address 2001:4178:2:1269::fed2 cannot browse either http or https, but the other two are working fine. Can you take a look on this ipv6 address? In addition, the traceroute seems to stop at Level3 cloud, and I think it is the problem with this address.
