After server 100

Well, if they're real servers, you can't really "delete" them...

what will the servers be numbered after 100? As 101 and above are all merged servers. I would guess s126 onwards?

The world as we know it will cease to exist. To steal a quote from from one of the great movies of out time:

Dr. Peter Venkman: This city is headed for a disaster of biblical proportions.
Mayor: What do you mean, "biblical"?
Dr Ray Stantz: What he means is Old Testament, Mr. Mayor, real wrath of God type stuff.
Dr. Peter Venkman: Exactly.
Dr Ray Stantz: Fire and brimstone coming down from the skies! Rivers and seas boiling!
Dr. Egon Spengler: Forty years of darkness! Earthquakes, volcanoes...
Winston Zeddemore: The dead rising from the grave!
Dr. Peter Venkman: Human sacrifice, dogs and cats living together... mass hysteria!
Mayor: All right, all right! I get the point!

But seriously, I think their options are to either reuse server numbers, or jump ahead quite a few numbers. I hope they just jump ahead numbers.

Also, when servers are to be merged, maybe they could hold a competition where people the players can pick a name for the new server.

My guess is they'll start deleting inactives and adding new players

Skipping server 1 again just to honor a few people who reminisce about it is not going to happen.

My thoughts exactly, anyone can say "Server [put server number here] is legendary, It must be treated higher than all the other servers which are technically exactly the same!"

this isnt just any server,. you guys just dont understand and never will

Okay elitist. We get it, you want to feel special. Here's a cookie, now run along.

Back on topic, Yes servers can be 'deleted' and they probably have been to make room for the merges and expanded demand for servers. Let's face it, s1 is probably s101 already, because to a company, they are just servers in a data center somewhere. There is no need to buy more just to keep the old ones in trophy cases.
