If you are confident where the loss is then the only thing you could really do within HN is email Daniel (dang) and ask him to replicate the issue and open a ticket with their upstream provider to check routes and for losses. hn@ycombinator.com

Outside of HN I suppose you could check the Nanog mailing lists [1] and chat servers to see if there is any discussion ongoing for those networks.

I decided to wait a bit, and it's fixed now by way of "americanis.net" no longer being on the path.
