Understanding what is actually happening
This is not one specific shard/server. It is however the server/shard that is up the longest after reset.
Ok so here is what is happening and possible fixes for it. Early morning ct there is a 10min reset that shuts down shards/servers and clears scores all rendered skins/mobs, turkeys, skitters ect. For the time being lets call them assets.
It is now 8hrs later the first server has been up loading these assets from thousands of people. By now a second server is engaged to compensate for increased play traffic. The 1st server remains up, but is now lagging due to a day of asset loading. This server however will not be reset till hours from now. Most jump off the original server giving it time to clear some of the assets, but untill reset it holds alot of them.
So how is it fixed or avoided? Well larger clans can just go to someone not lagging and on a newer server. Others can go to friends on newer servers. You can log out and log back in hope to get lucky. A trick that works really well if you can't get on is join a session or have someone invite you to join from in game on a good server.
Defiance has the largest open world and population at the same time than any games out there. It is why people don't want to give up on it. It's the same reason nobody attemps what they do because they know it will slowly become unstable and frustrating to player base. In d13 this caused huge memory problems crashing you every couple major arkfalls. Some fixes they used were generic skin textures (Dwayne) he was called. In 2050 they took another approach of not showing other players to reduce asset loading. Why do I see 100 turkeys and no players?
The fix is more powerful servers and more up at once, but thats not going to happen anytime soon. So a temp fix could be a designated mid day restart. Maybe the same time we get the new contract update take it down 10 minutes. Then do the same 12 hours later.
I hope they do look into a solution as this scares new players away. We have to explain in chat all the time what is happening. So think about how many give up because of this frustration.
