I've never seen this before. For the last 24 hours my root directory pages have been showing PR_grey but the rest of the site is still healthy. For background, it's a new site (January 05). The site has gone down really well. Another site has even thrown a sitewide link at it (without my knowlege). I don't want to publish the URL, but it's a unique content site about rusty pieces of metal. There is no duplicate content on the web, I've redirected non-www to www. htaccess and robots.txt look like other sites of mine which are doing fine. I submitted to about 2 directories, and have a tiny amount of co-op pointing towards it (maybe 150 views a day). Other than that it's all white hat. I guess the sitewide could have resulted in Google Bowling, but why only the root level. I have a forum in a sub-directory that still looks OK. And everything else looks sensible - the whole site shows up in Google search, and the site: search. This is not a ban. I'm not really worried, just interested if anyone else has seen anything like this before?
If your SERPs are unaffected I wouldnt be too worried about it. Sit it out it'll probably return back to normal.
It's been posted that there is some big update going on. It's also known that they throw alot of power at it on weekends by what I've read. I'm sure, like memorial day weekend, things will be affected. I'd go have a beer and check back monday.
Funny you should say that - just off for a beer now. Everything seems OK apart from the PR display. Just seems really odd that that's disappeared... Actually, the PR of the root has been showing less than the forum for a while. But it was showing PR. Wasn't memorial day last weekend?
Oh cool - we've moved over to the website review section. It's a slightly odd place to end up as I'm not sharing the URL. Never mind
