Here in Thailand I currently get the page below at http://www.rubyonrails.org and http://www.rubyonrails.com. The domain name registration seems to be ok, but there was an update yesterday (April 20th). And it's a garish parking page that in the colors of Django?! Is it some regional DNS screw-up? Am I mistyping Ruby?
UpdateJust checked via US-based proxy, the issue is confirmed, it's not a regional Asian DNS snafu.
Update 2The same happened last year and it looks like it happens every year around April 20th, April Fools + 20 or sth.
