I saw a post a few minutes ago by Brian Duff titled "We're Back!" that apologises for the fact the site has been down for quite a few days. I follow this site every day as there are a lot of good Oracle watchers and writers who's blogs are aggregated there.
I checked Brianís site earlier in the evening and it was still down but his blog post is timed at 05:25 (not sure what time zone though) so maybe the DNS propagation has not completed. The reason orablogs was down was because of an IP address change.
