DNS Problems

I seem to be having some DNS problems with this website. I don't think it's Dotster's fault because all the other subdomains on this box (like eikon.recursion.org) are working fine. Unfortunately, I do not know what the problem is. I can reach the site from some networks but not others at various times.

Update: Apparently my secondary nameserver doesn't yet know about this hostname. Hopefully, it will be resolved soon.
