yes, hacked by your isp who has somehow screwed up the .cgi mappings in that dir, or overloaded that dir, or they can't handle the traffic u get to it
to test theory to opening some graphics, i.e. noncgi/smile.gif
if they dont work then ur isp has seriously stuffed things up
and if ur hacked your page WILL load up, but it'll say:
"el33t h4x0rs, d@ l33t kr3w w4$ h3r3 & w3 ***0r3d j00"
it wont just load forever:)
