My interpretation is that uptime will remain sporadic until Monday. That doesn't mean they've just given up on it; just that they won't be able to completely fix it until then.
It's not a total loss of service (at least as far as I've observed)... I was able to update and view one of my sites (on vito) a few hours ago (it has since gone down again). And I successfully checked my e-mail (on murdock) just now.
My sites are back up.
Back down. Haha
