Hi,
Goof-head that I am, I took down wikimetrics for a few minutes just now. The reason was that I accidentally ssh-ed into the wrong box and updated to the latest version of the code. I thought I was in staging but I was in fact on production. No related problems seem to have come up.
I did notice an unrelated problem, which is that since our migration to the new puppetized version of wikimetrics, old reports are no longer saved for 30 days. I'm filing a bug and looking into that, please let me know if this is affecting you.
Sorry if I caused any trouble, drinks on me
Dan
