So I got back from my honeymoon last night.
This morning I had several e-mails from players unable to login and no statistics were being recorded.
Turns out I ran out of disk space.
I have corrected the problem and logging in and statistics all now work correctly.
I posted a blog post earlier stating it would take up to 2 days to correct, turns out I was WAY off on my estimate as it's resolved now :)
Enjoy playing :)
