Shouldn't have to use a VPN for a solution to this.
I am in Aus, and having the same install problem. It started with the patch yesterday, so I thought I would try verifying game files. Easy to do on steam, but I couldn't work out how to with uplay, so I just uninstalled it and let it reinstall overnight, except that it sticks at 12.35gb and nothing I can do will make it continue. Waste of time and energy. And data allowance.
Just another reason to be disappointed with Ubisoft.
