For those people that can't get tracking info from TNT, you need to change TNT site - it is the UK tracking site that is down. Click on "change" next to United Kingdom at the top of the page and select "United States". Then put in your consignment number on the first page. This has worked throughout the weekend (though without updating).
My status is much like others on here, shipped 1/7, delivery changed from 5/7 to 2/7.
However, in the last 15 minutes, TNT have updated to show it arriving in Arnhem in the Netherlands.
