Anyone else getting slung out of the NaNo site?

I went into the NaNo site this morning when it should have been quiet. I was logged out (never happened before) and it refused to recognise my password! I had to apply for a new one, changed it to one I can remember, then I was back in. Just been on again to update my word count, and I've been logged out again!!
Anyone else having this trouble?

It's not been a problem before this morning, and I was dropping in a few times a day to update word count and check mail. I've logged in again just now to update the word count, we'll see if I'm still logged in when I visit again tonight...
