In regards the connectivity issues with Stardock Central, Stardock.Com, Wincustomize.Com and other sites which Stardock hosts/owns.
At this time, Level 3 Communications and Cogent Communications are at odds. As a result, any net traffic exclusively through Level 3 connections to the Cogent network is not making it to its destination.
We'll see over the coming little bit whether they come to an agreement or other peering relationships are established to bypass to blockage.
The problem is neither on your end or our end. We are unfortunately stuck in the middle.
