FWIW, I don't get a blank page from perlmonks.org or perlmonks.net. That means, of the six permutations of the root URI ({www,}.perlmonks.{com,org,net}), only two are showing blank pages.

Of course, I've bookmarked and enter the site through the "Recently Active Threads" node on the dot-org anyway, so I wouldn't have noticed this even if I had been using one of www.perlmonks.{org,net}.
