I am not sure whether you refer to "nasaspaceflight" or the "SSM2007" website. Regardless, if it's SSM2007, it's more likely that it's blacklisted on the local firewall or network cloud. Other DoD networks do have access - I know that for a fact

I should have clarified: The SSM2007 site .. I'm sure it's somewhere deep within the US Army network somewhere; been like that for about a year now. I should run a traceroute and see where it actually dies just for fun. Anyway, it's real inconvenient to have to wait to come home to catch up on the daily forum issues.
BTW: Just got out of bed, having coffee, and now running back into work... what a fun Saturday it'll be.. Later!
