Over the last few days, I've had an intermittent problem where my watchlists on both w:en: and meta: come up as though I was loading the page a day or so ago. As in, it says "..the last X changes in the last 3 days" but then begins with "29 Sep 2004" and goes back from there.

Does anyone know why this is? Is it a result of overloaded servers? Or just some on-going maintenance? Or is there something more serious - a server with an incorrect internal clock, for instance?

Just thought I'd ask because a) it's a bit annoying and b) if nobody who had the power to fix it knew about it, it would carry on being annoying on and off for ages. So I apologise if this is something you're already working on.
