140.82.113.0/24 is visible in the global routing table:

  route-views>sh bgp 140.82.113.0
  BGP routing table entry for 140.82.113.0/24, version 62582026
  Paths: (19 available, best #4, table default)

The route is verified by RPKI so it's not a route hijack.

Edit: deleted traceroute

Your requests made it farther than mine - mine get to charter in nyc and die there

I’m in US east coast with a dev box in Helsinki. My dev box can still hit github.com, but I can’t at home.

[musha68k → alexeldeib]

Curious aside: That sounds like quite the roundtrip for day to day work. How do you cope with that, used to IntelliJ IDEs? ;D

[alexeldeib → musha68k]

Surprisingly, not that bad ;) just a cheap hetzner box.

[llimllib → alexeldeib]

What IP does it resolve to in Helsinki?

[Maxion → llimllib]

From Finland, but not Helsinki: 140.82.121.3

[alexeldeib → Maxion]

yep, same

[adnauseum → hn8305823]

This is so cool! I'm not at all familiar with any of this network stuff. Any good resources for learning these tools and when to use them?

Sorry to bother!

[ShamelessC → adnauseum]

TCP/IP Illustrated is a good start.

Thank you!

github.com for me returns 140.82.121.3 which routes fine in the uk, returning from

lb-140-82-121-3-fra.github.com

which from the distance and name I would assume is a frankfurt based load balancer. I get there from BT -> Zayo

I can reach that IP from Washington too, but github returns 140.82.114.3 and 140.82.114.4 from DNS at 1.1.1.1 on a Level3 handoff in Washington

Spot checks around the place show the first returned IP as pingable across the world

Bangkok, Dhaka, Jakarta - 20.205.243.166

Seoul - 20.200.245.247

Nairobi - 20.87.225.212

Kabul, Dakar, Amman, Amman, Cairo - 140.82.121.3

Moscow, Riga, Istanbul - 140.82.121.4

Miami - 140.82.114.3

[Maxion → iso1631]

Same from Finland, and same route. (Except my ISP instead of BT).

[iso1631 → Maxion]

They do have other peering -- that IP from my ISP in Jakarta routes onto Hurricane Electric in Singapore and then to github. From Sao Paulo I go to Atlanta, USA, then to Paris and Frankfurt on twelve99/Telia

found the neteng guy

[almost_usual → hn8305823]

I'm able to reach on 192.30.252.0/22.
