This affects all of the IPv6 addresses for us.archive.ubuntu.com as well (the addresses are mostly the same as security.ubuntu.com, excluding the two that actually work.)

It would be less of a concern if apt automatically fell back on the IPv4 stack, but right now the only way for my machines to receive updates is to manually disable IPv6. This is cumbersome--and in the case of security updates, potentially dangerous.
