Ah yes, I'll always have a special place in my heart for those

In contrast, talking to a few DNS servers gives you an end-to-end
test of how well the service is working. You still depend on the
answers being correct, but you can intuit a lot from whether
or not you actually get answers, instead of sitting around twiddling
your thumbs thinking, "gee, I sure wish that routing update would
get sent out so I could use the 'net."
Anycast isn't the only thing possibly stuck waiting for routing
convergence... Let's not get carried away here.
