Google not showing indexed URL's anymore?

I'm not sure if this is the same for everyone but i noticed yesterday that google was showing my list number of indexed urls as 0, i also use IBP and checked with that and all my link seem to be showing as normal in google, and my site is still indexed.

I had a look around and found that few people had the same issue which seemed to have started yesterday, i just wondered if everyone was experiencing the same issue or just a few random people?

Webmaster Help Forum Announcements: Known issue: Sitemaps indexed URL count showing zero indexed URLs

And there was me on another mission with 86 indexed pages in my site map showing and dropping daily with traffic still on the up again.

Oh well, another dont panic moment missed.

I woke up. I checked.
without www. - started crawling indexed urls
with www. - Still 0 indexed urls.
What do you recommend? Should I do something about it?

I checked my sitemap pages. Set to 30k per site map. Some were just over the limit I believe.
Yesterday I had 86 indexed pages, today I have 85,900.
It might be something simple like that at fault.
