Looks like they're cutting back on servers for BWE 3.
As you’ll see, there will be fewer worlds available initially than we had during BWE2. Why do we have fewer worlds for a much larger beta event? There are a few different reasons for this, ranging from being able to have a larger player limit on all worlds, to a shift in focus for how we utilize our server power.
Many of you may remember our blog post prior to BWE2 that mentioned how we had acquired a ton of new servers in order to support the number of players we expected.
As our esteemed Lead Server Programmer Dr. Stephen Clarke-Willson put it recently, “Quite frankly, we made too many worlds for BWE2 just because we could and not because we should, and thus we had a lot of low population worlds. This time around we’re focusing our new CPU horsepower into fewer, more populated worlds.”
I tried to post the list here, but it's in a table and got all jumbled and I'm lazy.
