Google Sitemap - Pending status

I submited two blog, both are in pending status since yesterday. I thought it might be server update or something, but it's still under pending today. I was worry and went to visit Google Sitemap's blog. Nothing were mentioned about the pending status.

Then i went and check Google Groups, google-sitemaps. Felt relieve, it was not only me who is facing "pending" status. But still, no official announcement or explaination being made of why the Sitemap status turned into pending. Hope it's nothing...
