acf_: both are in the mix at least i think level3 is still in the mix actually i think you're right. a lot of routes go over ntt though. yeah, even traceroute to www.level3.net goes via ntt and of course https://bgp.he.net/AS25795 kinda sad to see level3 replaced with the most asshole transit provider :P i use 4.2.2.2 as a standard level3 address some providers like to put their main web page on a cdn
