Are CircuitCity's and TigerDirect's pages down??

So, I've been trying to get into both webpages with no luck twice already (last week, & today), I'm using more than one browser... Chrome18 & IE9... Chrome says the page is taking me to a loop, IE says the typical "IE can't display the wp"

I pinged them (thru CMD) got positive response (4pctks sent & received), still I can't get into the webpages...

Any ideas why??
Has someone had the same problem lately?
