Datacentre has notified me of the following:

We are having reports that some servers are locking up. We are currently investigating this issues. There is no current ETA on resolving this issue

and then:

Upon closer inspection for the pervious issue we do not believe that we will be able to resolve the issue without a reboot. As such we are performing an emergency reboot of the gateway at 10:15am. Services should be restored within 30 minutes

Some more modifications have been made to the box, in order to try improve stability and things.

Removed nether, and other little optimisations, such as updating bukkit.

Things should work much better now.

[Statistics vaild 1 week till 7th Feburary]

The current build on server [denspark] is unstable, if this server is down, please use classic instead which can be connected at: classic.crazy-fools.co.uk . Classic uses an earlier [and more stable] build.

denspark is now back online.

denspark [server.crazy-fools.co.uk] appears to be offline due to a crash that can't be solved remotely, it the meantime, please use classic.crazy-fools.co.uk

Donators and above can now access the nether by typing /world nether

Use /world normal to go back.

We've built a nice little safe spawn in the Nether, with a safehouse.
