Been here since 09 (Mod 9) and experienced various types of game lag throughout the years, many of which I would hardly run into due to having a rigorous gaming rig and a decent connection.
The game suddenly freezing is nothing new.
However, the more recent type of "freezing" game lag, is not quite the same as previous ones where no one is moving or doing anything else. So if the developers are reading this, this is definitely something not quite the same.
Quick preliminary tests show that other movement in game can and still happens and will update onto your screen even whilst your actions do nothing in game. Which suggests our client is not entirely frozen, but what "we" - the player, attempt to do in game - is entirely frozen for the duration and out of sync with the game server (since we can be bounced back a second or two's worth of movement and can even see the server update the enemies and even other players to move them to our last position and attack, continue the quest, etc).
Had this been an entire game server freeze, like in the good old Baba raid where it can just freeze entirely and no one but enemies can do anything, this would even be "normal" for DDO. However, here, recently - for me, this new lag is not the same.
Now, the last week or so here in the UK, there has been increased use and activity on the networks because of King Charles coronation. So it "might" be possible that everything is all hunky-dory in my home network and over with SSG servers, but it's actually the network in the UK that's acting up. I can't rule that out.
Or, there's something very off with U59 given it only started after then. And only getting worse throughout the weekend(s).
