Wikimedia Stats, run by Erik Zachte, seems to be down today (403 error). I hope this means this valuable resource is being upgraded:
Hi Tony, wikistats will migrate to a new server, hopefully in January 2012. I hope this will give enough capacity to process full archives again, instead of only stub dumps. Cheers, Erik Zachte (talk) 13:21, 25 December 2011 (UTC)
Thanks, Erik. I look forward to this, if the capacity is there. Tony (talk) 14:22, 25 December 2011 (UTC)”
UPDATE A few hours later and they are back with but only up to 2011-12.
