this means there were 8 nodes that may have been on the forked chain too, why? I always used to have 8 active connections
EDIT: After reverting to October backup it synced to main chain.
I suggest to improve the client in this way from GLD (idea of new defense system + fixes) to prevent unexpected forks:
