No, was actually stale.
I've changed the flagging of it.
On the web it was an immediate orphan coz it was already stale, but any block submitted that isn't worked on is auto-flagged as orphan until I manually check everything then flag it.
I've looked through everything to be sure, but yep it was a stale share.
The share came into the Silicon Valley node at 2017-08-10 20:28:30.533 UTC
But all nodes and the main pool had already switched to the poo block by then.
Kano, do you advertise your pool bitcoin IP addresses so that others can connect to it to help with rapid propagation to reduce the possibility of stales? I have a full node running in the SW part of the US that I can force connect to your node if it would help.
