RiiConnect24
RiiConnect24 is a custom WiiConnect24 replacement. There are currently two servers: one ran by Billy549 and another ran by AwesomeMarioFan and Larsenv.
Connecting to the server
To connect to Billy549's server, use DNS 185.99.132.59. To use AwesomeMarioFan and Larsenv's, use DNS 168.235.71.66.
Current service
Both servers have News Channel dumps that are from 2013, and Billy549's has custom announcements, due to Ciapa finding the symmetric key. However, not everything is working, due to issues with some servers.
Known issues
Weather Channel
Weather Channel, at this point, does not work, due to bad dumps. The authors are trying to find the keys, however, to create their own files.
Wii-to-Wii mail is not working yet, due to check.cgi having weird values that the authors need to learn. If anyone has a packet dump of connecting to WiiConnect24 and checking for mail (before WiiConnect24 "shutdown") even if it has no HTTPS patches, please contact Billy549.
