If you are having trouble connecting to WarZ (launcher stuck) there was NOT an update
patch notes are still at 12.21.2012, and you can still connect.
your DNS is wrong, looks like someone over at thewarz messed up a setting, all the urls point to 127.0.0.1, you can correct them by changing your DNS or entering IP overrides manually in your hosts file
the correct IPs are
108.162.203.133 thewarz.com
108.162.203.133 forums.thewarz.com
108.162.203.133 www.thewarz.com
69.16.143.102 account.thewarz.com
66.180.197.58 api.thewarz.com
your DNS will update automatically, however it can take up to 72 hours, most update within an hour though.
