My specific point from TFA was that they had 100 anycasted IPs all over the world, the distance to their dns server shouldn't matter. remarkably *all* of my tcpdump traffic for the last 60 seconds was ipv6, the only ipv4s I can see were 104.244.42.193 104.244.42.2 which are twitters. (really shocking they have no ipv6) https://bgp.he.net/AS13414#_prefixes really awful ping times over verizon 5g root@balthazar:/home/d# ping 104.244.42.2 PING 104.244.42.2 (104.244.42.2) 56(84) bytes of data. 64 bytes from 104.244.42.2: icmp_seq=1 ttl=52 time=268 ms 64 bytes from 104.244.42.2: icmp_seq=2 ttl=52 time=89.5 ms 64 bytes from 104.244.42.2: icmp_seq=3 ttl=52 time=111 ms 64 bytes from 104.244.42.2: icmp_seq=4 ttl=52 time=134 ms 64 bytes from 104.244.42.2: icmp_seq=5 ttl=52 time=158 ms 64 bytes from 104.244.42.2: icmp_seq=6 ttl=52 time=59.6 ms On Sun, Nov 13, 2022 at 2:50 PM dan wrote: > It's pretty interesting and though they were 'surprised' at the results, > as someone who lives 'a lot' of hops from major datacenters this makes > perfect sense lol. > Here's a local Spectrum circuit to twitter: > [image: Screenshot 2022-11-13 at 3.45.00 PM.png] > and here's off one of my Lumen fiber circuits: > [image: Screenshot 2022-11-13 at 3.45.19 PM.png] > > 41ms is 'fine'... except this is about the best it gets here to a major > service that lives in tons of datacenters off a DIA 10G fiber circuit. > 104.244.42.65/.1 are the two DNS records I get for twitter and have the > same numbers between them. > > Also, not to 'brag' here but I'm rocking that solid 41ms and the furthest > edges of my network are 15ms out so my wISP service spanks Spectrum in > latency every time.
