Based on the image they tweeted, I don't think they are doing much
filtering; the Syrian prefix was spread to a number of countries and AS. If
you have good US connectivity the impact seems limited due to better AS
Paths winning, but for less well connected prefixes I'm assuming it's more
up in the air.
