I have a domain www.aieseccareerday.com, which times out whenever I try to access it. However, my sub-domain (ogx.aieseccareersday.com) responds just fine. I need to get this fixed as soon as possible.
Both domains are working for me. (please note the typo in your above post: careers should be pluralized for the domains, as you have it in the subdomain)
I would suggest clearing out your cache and try loading the pages again. Hopefully that will fix everything.
