To the Technic staff:
Your DNS entry is likely bugged. mirror.technichpack.net is currently set to 206.217.207.0 which is generally not correct. Your DNS entry has a TTL left of just under 4 hours. If people attempt to download directly from your server at the following link, it will probably work: http://206.217.207.1/files/TechnicLauncher.exe
However, then they are faced with the problem that the launcher may try to pull files from the same DNS entry. They could fix that by changing their hosts file on their PC to point mirror.technicpack.net to 206.217.207.1, but I'm not going to assist anyone on doing that. If you're one of the users reading this and don't know how, google it and figure it out or wait the 4 hours and hope they fix their DNS record by then.
If you want my honest opinion, set a lower TTL on your DNS entry, and don't let people update your records if they don't know what they're doing.
