I checked your website and it seems to be working fine from here. It seems to be a Bootstrap demo, is that what you uploaded?
It could be that you’re still suffering from DNS cache. The 72 hour statement is not a hard rule. Well behaved networks should show your site within 24 hours. Unfortunately, many networks are not well behaved, but 72 hours should be large enough as a margin. But I’ve also been told it can take weeks for some unlucky few.
But it could also be something else. To help narrow that down, can you tell a bit more about what you’re being redirected to?
You could also try to connect through a VPN and see if that helps. If there is any misconfiguration or block on your connection, a VPN should help circumvent that.
