Dear Sirs,
Wikipedia is a large, collaborative project to produce a free encyclopedia. There are currently nearly 100,000 articles, and about 200,000 page impressions per day.
As of last weekend, all Wikipedia articles seem to have disappeared from the Google index. Wikipedia article URLs look like this:
http://www.wikipedia.org/wiki/<article-name>
We are not aware of an outage that might have caused the Google spider to miss the pages. I would much appreciate it if you could shed some light on the issue.
Sincerely,
Erik Moeller
