36 hours....servers went live at 18:00PDT, next one was 6:00 PDT, then 18:00, 6:00, etc. It hasn't been perfect though, I think one time it seemed they reset sooner
They should reset again tonight at 18:00PDT or in that range
This is actually slightly off. I noticed yesterday morning I was able to get new leves at 7:00 CDT, when it should have been 8:00 CDT, assuming leve timers started at 18:00 PDT. I didn't check before then, so I don't know if they reset before 7 or not. Perhaps SE brought the servers up before 18:00 to do some maintenance on them or whatever, thus starting leve timers sooner. Just a guess.
And I'm pretty sure they're on a 36 hour cooldown. With the way 36 hours flow, it'll sometimes seem like you get leves two days in a row, but that's simply how 36 hour intervals pan out. Go with the 18:00 PDT example. The rotation would be:
21st 18:00 > 23rd 6:00 > 24th 18:00 > 26th 6:00
As you can see, it goes 21st to the 23rd, to the 24th. It "appears" to take two days on the first one, then just one day on the second. It's simply because the cooldown started late in some time zones paired with the 36 hours, which makes it sometimes seem shorter. Edited, Sep 27th 2010 6:59am by TheLufia
