RSS feed not receiving new articles

Hello.

I’m running a blog, https://www.fashiongeekette.com under WordPress 3.0.4.

Since yesterday afternoon, my RSS feed is not containing my new posts anymore. I really have no clue of what is going on. I have not changed anything. The only thing that happened is that my hosting company has had some downtime.

I have submitted the problem to them but have the feeling that I’m shooting in the dark.
Is there anyone that could help me out, please ?
Thank you very much.
