We are sorry that we didn't inform you earlier. Our mirror: mirror.timtal.com.tr will be down for a week or two due to some issues caused by recent changes in our server (someone messed up the firewall). We're on it and trying to fix things as quickly as possible. 

I'll send out an update when everything is back up and running.

Thank you for your patience!
