I've tried archiving it on 'archive.org' and even there it caused my browser to sporadically freeze. It did create a snapshot, but trying to visit it just times out archive.org.
The 'archive.today' service just times out after 5 or so minutes.
Since it's just html i wonder why there is this reaction, shouldn't above the fold load and then slowly load what's below the fold? Obviously sites like this are a rare occurrence, but it seems something changed where processing sites like this has become a problematic issue. It makes me question whether if this could be exploited on palemoon users that could lead to the same issue where the example trick was done where a large amount of divs in CSS could restart apple devices.
