Since the last update there is a bug in the skylands. When people fall off an island there, they do not die. They logout and later log back in with a negative y-value.

2011-08-08 00:47:47 [INFO] <user> <ip> logged in with entity id 2147226 at ([skylands] 475.0939776106811, -73.83340857907588, 33.99777082139628)

From there on, the server is bust:

2011-08-08 00:48:33 [INFO] Connection reset
2011-08-08 00:48:45 [INFO] Read timed out

Because this has been repeating, I had to shut down the skylands portals for now. If you are there, you should be able to get back with /spawn. They will remain closed until I find a solution to this issue.
