For folks who have not been following the saga on http://wikitech.wikimedia.org/view/Dataset1 we were able to get the raid array back in service last night on the XML data dumps server, and we are now busily copying data off of it to another host. There's about 11T of dumps to copy over; once that's done we will start serving these dumps read-only to the public again. Because the state of the server hardware is still uncertain, we don't want to do anything that might put the data at risk until that copy has been made.
The replacement server is on order and we are watching that closely.
We have also been working on deploying a server to run one round of dumps in the interrim.
Thanks for your patience (which is a way of saying, I know you are all out of patience, as am I, but hang on just a little longer).
