My Backlinks disappeared from Google

[petra]

My site is listed in the DMOZ and Google directories in two different categories with a PR of 5 and 6 and and they were for a while included in my backlinks with google. I also have other PR 4 and 5 sites linked to mine as well as my own interior pages that were all showing on my Google baclinks until a week ago.

For some strange reason, last week all these links disappeared from the site info (backlinks) on the G toolbar.

The only major thing I did was move my site to a dedicated server could this be a reason?

Any clues as to what is happening will be very much appreciated :)
