No, it isn't.

Hmm, having double checked, I can read it if referred via HN, I can read it direct via my ISP, and I can read it direct via a VPN in a couple of global geolocations.

That doesn't help you directly, but perhaps that might help tracing your issue.

Unless you were running a Ceci n'est pas une pipebomb bit that flew over my addled head ...
