So far the new network hardware upgrade on the EU servers is a big improvement in general.
BUT traveling from normal/high population zone to a low pop zone results very often to "the" ERROR (can't log to game server, make sure you have network)
which means can't connect to zone partitioned server.
Login to the game is not the problem, zoning is, and trying 2-3-4 times to port to a low pop zone can result in a buffer overflow and ofc creates a BLEU SCREEN Netio.system in my case.
(memory dump is 1.5 to 3 gb depending how many times you tried to port in or out the zone)
So the software controlling the zone partition population/density fails (or is corrupt)
Again this is not happening when I play on the NA servers.
Please check and compare this software on both NA and EU servers.
