Adrian is aware of the problem, some setting on our new server isn't happy so the server gets overwhelmed after a while.
If the site doesn't load for you, just drop me an e-mail at:
Problem will be resolved soon enough, sorry for any problems it causes. If anyone is planning to write a long journal entry, I would recommend highlighting all the text, and selecting copy (usually under edit), before submitting it. That way, if the server happens to have gone down, you can open Word or some other text edit, and paste your journal in without losing anything, and then just copy and paste it again when we're back up and running.
