There are some problems with the comment system and the MovableType publishing system in the recent two days. I called CompanyCN, the hosting company I chosed and they told me a site on the same server with mine upgraded their database scripts and is using up all the system resources. So my poor web is impacted, as all other sites.

I signed up ipowerweb. I hope I can switch to the new server very soon. I feel very bad for this incident that many visitors may have spent a lot of time to write comments on this site but it was lost during the error.
