Why are the IFRAME elements nested? Is this a bug?

Only four iframes? They have to go deeper. – user157130 Jul 9 '11 at 20:56
+1 Nice catch. The servers are currently offline stuck in an infinite iframe loop. – M. Tibbits Jul 10 '11 at 3:18

This happens because the <iframe> loads the offline page specific for the site you're visiting (or sketchy for beta sites). However, in cases like today we took our entire network offline, including, so the offline pages the top level page load's in its <iframe> were...itself, being served by the load balancer, loading another frame again.

I added a check for this, and we'll print out a nice message instead of continually loading nested frames in the future.
