Since our hosting service provider is not so stable with their network and service, I just moved the site to a new server located in a new data center. It should increase your visit speed a bit, and we should have less down time.
Because the site been moved to a different server, there might be some problems. Please report here if you find any.
Known problem: If you linked to a small/large photo on this site somewhere else, chance is you won't see it on the other site. But if you visit the photo page for the linked photo on this site, the small version will show up again on both sites (Once you visit a photo page, a small version will be generated if not exist).
This is because the data volume is too high to move from old server to the new one, so it's better to regenerate them from original photos.
Thanks,
Ken
