This is a problem with fidelity.com's DNS. Their authoritative DNS servers are:
fidelity.com. 451 IN NS j4.nstld.com. fidelity.com. 451 IN NS l4.nstld.com. fidelity.com. 451 IN NS ns1.fidelity.com. fidelity.com. 451 IN NS ns3.fidelity.com. fidelity.com. 451 IN NS ns4.fidelity.com. fidelity.com. 451 IN NS a4.nstld.com. fidelity.com. 451 IN NS f4.nstld.com. fidelity.com. 451 IN NS g4.nstld.com. fidelity.com. 451 IN NS h4.nstld.com. and none of the nstld.com ones know anything about retail.fidelity.com: [EMAIL PROTECTED]:~$ host -t ns retail.fidelity.com j4.nstld.com Using domain server: Name: j4.nstld.com Address: 192.48.79.33#53 Aliases: retail.fidelity.com has no NS record Yet if the query runs against one of the three listed fidelity.com servers: [EMAIL PROTECTED]:~$ host -t ns retail.fidelity.com ns1.fidelity.com. Using domain server: Name: ns1.fidelity.com. Address: 192.223.252.11#53 Aliases: retail.fidelity.com name server dns3dccfw01.fidelity.com. retail.fidelity.com name server dns3mr4fw01.fidelity.com. retail.fidelity.com name server dns3mk2fw01.fidelity.com. So I can only assume that the Windows/other resolvers are being a little more persistent, or lucky, or getting a cached response. ** Changed in: firefox (Ubuntu) Status: Unconfirmed => Rejected -- firefox cannot locate server, "myfidelity.members.fidelity.com". https://launchpad.net/bugs/51014 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
