Bored Aussies is back up apparently. If you still have WC3 installed you can hop on at any time; for now at least.

Same old gateway is needed to log in. If you didn't log in prior to 2014 then you will need to change the gateway manually to pvpgn.boredaussie.org instead of of pvpgn.boredaussie.com (the old gateway) in order to connect.

If you need help doing this, open up Regedit:

1. Find the following registry: HKEY_CURRENT_USER -> Software -> Blizzard Entertainment -> Warcraft III (or search if you're ceebs)
2. Click on "Battle.net Gateways"
3. You should see a bunch of gateways already there. At the bottom there should be one for BA:

pvpgn.boredaussie.com
10
Bored Aussie

4. Change pvpgn.boredaussie.com to pvpgn.boredaussie.org. It should now look like this:

pvpgn.boredaussie.org
10
Bored Aussie

5. Click OK and close Regedit. Now try to boot up WC3 with the BA launcher (w3l.exe) and log in as per usual.
