I fixed it (and Netflix) by turning off IPv6 for all my users... but any chance this is a path MTU issue causing the apparent hang?
I fixed it by using the rpz feature of bind to disable the AAAA record for www.pay.gov. I lookup the real A record, and then put www.pay.gov IN A %s into the local rpz zone. That suppresses the AAAA record, so local clients are forced into IPv4 for that site. That allows them to use IPv6 for other sites. path MTU - hm, I need to check that. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAlgsz0YACgkQL6j7milTFsEbpwCgiJwZm3R/0VowqNFu4afHwPRq siwAmwdAj2YCLnlNQAs5Q5E5hcthaoiP =yqXb -----END PGP SIGNATURE-----
