We are the primary DNS servers for the ben.edu domain. We seem to be having an issue with an AT&T server that is responding with incorrect A records for www.ben.edu<http://www.ben.edu> and ben.edu. What it SHOULD be the response: nslookup www.ben.edu Server: 63.250.224.66 Address: 63.250.224.66#53 www.ben.edu canonical name = ben.edu. Name: ben.edu Address: 38.100.120.100 What 12.127.17.83 is responding with:
www.ben.edu Server: tbru.br.rs.els-gms.att.net Address: 12.127.17.83
Non-authoritative answer: Name: www.ben.edu Address: 208.91.197.132 This appears to be affecting only iPhones and iPads on the AT&T network. Is anybody else having problems with this? Are there any AT&T people on this list that can help?

Looks to be right now.

Nope. Depends on from where you ask (presumably the AT&T resolvers are anycast).
