I have installed a new certificate on the secure side of XaoxNet so you shouldn't need to install a certificate authority. I have also updated Drupal to 6.28 for a security fix and update RoundCube webmail to 0.8.4 as a general upgrade. RoundCube now has a plugin that allows you to sync your Google contacts.
As always, let me know if you have any trouble.
I'm beginning the roll-out of IPv6 for Xaox.Net. So far this web page is available via IPv6. You can check your IPv6 compatibility on the left in the "IPv6 Test" box.
If your ISP hasn't rolled out IPv6 and you want to get started, checkout the Hurricane Electric Tunnelbroker.
