The following announcement was just released on the QuadNet website:
In order to better serve the QuadNet D-Star Routing community, we are moving our D-Star Routing IRC Servers. The new URLs for the IPv4 and IPv6 IRC servers are ircv4.openquad.net and ircv6.openquad.net, respectively. There will still be a diminished server operating on rr.openquad.net to fulfill the login needs of clients still using that address, but it will no long provide IRC update messages to its clients. In other words, clients still using rr.openquad.net will no longer be able to find IP addresses for their desired routing targets. If you use routing on QuadNet, be sure to update the IRC routing server name in your hot-spot or reflector software. If you operation a Smart Group Server or are STARnet Server, you will also need to update those clients. If you don't do D-Star Routing, no action on your part is required. This move will not affect REF, DCS, XRF or XLX linking to any of our reflectors, XLX307, XLX587, XRF735 or XRF757.
I just pushed up a new version. If you are using the default values for connection to our ircddb server, you will need to do an uninstall, git pull and install. If you are operating in dual-stack mode (IPv4 and IPv6) you just need to update your irc connection server hostnames with qnconfig and restart your system.
