It may just be me or my internet, but I tried this specifically to see the effect and it was a very slow escape (seemed delayed starting to load, and then loading the escape page).

I came to say the same thing: I love the idea of the quick escape, but some of the sites take way too long to load. They should prioritize sites with the fastest loading (smallest footprint) over some of the jokey-er websites like "43 Gifts for Every Type of Boss."
