We had an attack, but as we can see, it didn't do the attacker any good.
Some wallets have strayed from the right chain, but the main nodes are not affected.
Except that the number of connections to the network has decreased for some time.
Some coins have already been easily destroyed by such attacks (e.g. Deviantcoin) but DMD became only stronger.
I don't know if node=188.68.52.172 is a main node??
Its in your posted config file Pg1..
I removed it from mine but it still shows up..
I suspect it is a main node and its definitely having issues..
check your peers list..
I'm down to 4 connections and one is that node...
