@Commandojoe, the Warcraft III Classic game has been merged with Warcraft II: Reforged. Could you try the links on this thread instead?
@BarristerCat, would you be able to try an alternative connection to see if this helps? If a different region link does not resolve the issue, we may need to check on the connection to the patch servers. Could you include a traceroute and pathping test to us.patch.battle.net?
Copy and paste the text file created and paste it between two ~~~ like so:

Traceroute/Pathping Here

If you have issues pasting here, use Pastebin and post the end of the link. (ie. 123456 for pastebin.com/123456)
