The attack is reported on miningpoolhub: "- Bitcoin Gold network is under attack. As there's many orphan blocks generated, profit may decrease temporarily."
I have personally been affected by the attack, my funds are being held up (for over 8 hours now with 0 confirmations) and I don't know if I will get them back!

Still no info on other channels and it looking transactions are moving smoothly I didn't see any Orphan block. Anyway thanks for reporting this ongoing attack but it seems nobody using this coin at the moment.
Lots of orphan blocks are showing up on peoples transactions

This is from my personal transaction of almost 16 BTG I sent about 9 hours ago:
https://btgexplorer.com/address/GXD3h6ZV71PW4K1g5xLAWXKZNV1iofCZ3V
The transaction was originally going through and got up to 5/20 confirmations on Bittrex, but then reset back to 0/20. Went up again to 3/20 and reset again. Now it sits at 0/20.
