WoW realm queues and server age

If you ever tried to log on to one of the more populated realms (servers) of World of Warcraft during prime time, you know them: Waiting queues, telling you that you are player number 163 waiting in line to log on, and giving you an estimate that this might take 24 minutes. Apparently these queues have been put in place by Blizzard not only to prevent overloading the servers, but also due to game design reasons. So ideally the queues prevent not only lag, but also zones becoming overcrowded, with too many people hunting for the same mobs.

Of course for that to work you have to assume some sort of player distribution over zones. Letting, lets say, 3,000 players on the server only prevents lag and overcrowding if these 3,000 players distribute themselves over the world in a "normal" fashion. The world event of the gates of Ahn'qiraij opening was a good example of how that could fail, because a much larger percentage of players gathered in Silithus than normal, causing horrible lag.

So queue or no queue, on the first days after the Burning Crusade expansion goes live, we can expect lag and overcrowding problems, because people will be concentrated in 3 zones: The draenei and blood elf newbie zones, and Hellfire Peninsula for all level 60 players. I thought I could escape overcrowding by going to an instance, but that might have been optimistic. On the beta server I already got the message once that I couldn't enter the Blood Furnace instant, because there were already too many groups in that instance. So there seems to be a limit on the number of players the instance server can handle.

But what I am even more afraid of is having to wait in a queue. Blizzard will raise the cap of how many players are allowed per server by 25%. That will probably be sufficient for the latest and newest servers, but I doubt it will suffice for the older servers.

By the time the Burning Crusade comes out, the oldest World of Warcraft servers will be over 2 years old (3 months less for the oldest European servers). During these 2 years a lot of people stopped playing WoW, but they still have inactive characters on the servers. Blizzard keeps inactive characters indefinitely. So the older the server, the more inactive characters accumulate. The Burning Crusade will most certainly cause a large number of players to resubscribe, like after every major content patch. So the number of people trying to get online on an older server will be much larger than the number of people trying to get online on a newer server.

As my main character, the Horde priest, is playing on one of the oldest European servers, part of the original batch of servers that were available on the first day of World of Warcraft in Europe, I'm afraid that I will run into major queue problems. That is especially annoying when you finally get in, but then get disconnected for some reason. Sometimes the game will allow you to bypass the queue and reconnect immediately. But we had several raids where somebody who lost connection only came back 20 minutes or more later, due to having to wait in the queue. These queues might get 1 hour or more long after the expansion comes out. Not a very appealing prospect.

Hint: the limit in instances is only in the beta as their server hardware isnt as big as the final hardware park.
 
The first poster is correct, if not exactly tactful. :P Also, two things to consider:

Data is not processing power. Old, unused characters aren't going to affect the usability of the servers. They may take up storage space (that isn't actively ON the server in the first place) but they're not being accessed so don't affect users at all.

Secondly, I don't think there ARE any of the original servers left, in the EU or the US. All of them have been migrated to the new server design, as far as I know. I could be wrong, but I pay attention to the little 'sticky notes' that Blizzard puts up on their login page and have seen dozens of servers being brought down for 'extended maintenance' as they 'upgrade hardware'.

You should be OK on both of those counts. The thing you should be worried about is the tens of thousands of players logging in on their level 60 players to experience Outland. You're going to run into two problems, server overload (inescapable) and bandwidth. ICK.

They are if their owner decides to resubscribe, because the expansion rekindled his interest in WoW.

The hardware has changed, but the old realms are still there. This isn't a hardware issue, it is an issue of how many players want to play on the same server at the same time. What I am saying is that older realms have more inactive characters, and if on both old and new realms lets say 10% of the inactive players resubscribe, it causes a lot more trouble on the older realms.

Good point, are you sure of that? How many people *can* play in the same instance at the same time? I know that some raid instances get laggy when too many guilds are raiding at the same time.
 
The instances are on special instance servers. They are optimized to run one instance in many "copies". Some servers run more than one type of instance (lbrs/ubrs/brt), some only run one, depending on how popular they are. Instance servers are shared, ie. all realms use the same instance server park. That way it can be balanced.

Btw, the downtime we had today isnt only a hardware update, its also to prepare the realms for burning crusade.

Sorry if I wasn't tactful in my first post :)
 
Not with Tobold's new hardware -- he isn't going to be experiencing graphical lag. =) But generally speaking, you're right: it will affect some users (old hardware) than others.

Tobold wrote of a inequality between people who can buy BC and those who cannot afford it. Maybe there's a subdivision in the BC people, that only those with new machines will really be able to experience the new content, at least in the first few weeks.
 
I already have 1 hour queues on Khaz'goroth.

Last night I logged in, watched episode 4 of BSG and then still had to wait to select a character...
