IPv6 on tridex.net is broken

[benpicco]

If you add the tridex.net repo on a machine with an IPv6 connection, it leads to long delays (till the timeout kicks in and it switches to IPv4) when updating because while the domain resolves to an address (2a01:488:66:1000:2ea3:48b1:0:1), it does not answer any requests.
