-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello Anssi, Would you like to share how Cent OS team determine the mirror location by an IP address? Let's pick an example, softlayer has an IP test on Mexico (speedtest.mex01.softlayer.com), but yes, the traffic is through US than directly to Mexico. Possible it's IP Transit, since MIE (Mexico Internet Exchange) have same traceroute details. === Mexico Internet Exchange $host -t a mie.mx mie.mx has address 199.48.226.6 $whois 199.48.226.6 [Querying whois.arin.net] [whois.arin.net] # # ARIN WHOIS data and services are subject to the Terms of Use # available at: https://www.arin.net/whois_tou.html # # If you see inaccuracies in the results, please report at # https://www.arin.net/public/whoisinaccuracy/index.xhtml # # # The following results may also be obtained via: # https://whois.arin.net/rest/nets;q=199.48.226.6?showDetails=true&showARI N=false&showNonArinTopLevelNet=false&ext=netref2 # NetRange: 199.48.224.0 - 199.48.227.255 CIDR: 199.48.224.0/22 NetName: MEXICO2 NetHandle: NET-199-48-224-0-1 Parent: NET199 (NET-199-0-0-0-0) NetType: Direct Assignment OriginAS: AS395565 Organization: Mexico Internet Exchange (PT-323) RegDate: 2010-11-03 Updated: 2016-10-21 Ref: https://whois.arin.net/rest/net/NET-199-48-224-0-1 OrgName: Mexico Internet Exchange OrgId: PT-323 Address: 5872 Owens Ave City: Carlsbad StateProv: CA PostalCode: 92008 Country: US RegDate: 2015-07-13 Updated: 2016-10-12 Ref: https://whois.arin.net/rest/org/PT-323 OrgNOCHandle: NETWO7910-ARIN OrgNOCName: Network Operations OrgNOCPhone: +1-720-708-1835 OrgNOCEmail: noc at mie.mx OrgNOCRef: https://whois.arin.net/rest/poc/NETWO7910-ARIN OrgAbuseHandle: NETWO7910-ARIN OrgAbuseName: Network Operations OrgAbusePhone: +1-720-708-1835 OrgAbuseEmail: noc at mie.mx OrgAbuseRef: https://whois.arin.net/rest/poc/NETWO7910-ARIN OrgTechHandle: NETWO7910-ARIN OrgTechName: Network Operations OrgTechPhone: +1-720-708-1835 OrgTechEmail: noc at mie.mx OrgTechRef: https://whois.arin.net/rest/poc/NETWO7910-ARIN # # ARIN WHOIS data and services are subject to the Terms of Use # available at: https://www.arin.net/whois_tou.html # # If you see inaccuracies in the results, please report at # https://www.arin.net/public/whoisinaccuracy/index.xhtml # And I tried to traceroute the IP from cogentco looking glass and select Mexico Router (http://www.cogentco.com/en/network/looking-glass) using IPv4 Test. traceroute to www.mie.mx (199.48.226.6), 30 hops max, 60 byte packets 1 gi0-7-1-19.99.rcr21.mex01.atlas.cogentco.com (66.250.250.9) 0.750 ms 0.752 ms 2 be2692.rcr21.mfe02.atlas.cogentco.com (154.24.23.25) 12.952 ms 12.956 ms 3 be2888.ccr42.iah01.atlas.cogentco.com (154.54.47.45) 23.998 ms be2887.ccr41.iah01.atlas.cogentco.com (154.54.47.33) 22.499 ms 4 be2927.ccr21.elp01.atlas.cogentco.com (154.54.29.222) 38.106 ms 38.111 ms 5 be2929.ccr21.phx02.atlas.cogentco.com (154.54.42.65) 44.452 ms 44.462 ms 6 be2932.ccr22.lax01.atlas.cogentco.com (154.54.45.162) 56.220 ms be2931.ccr21.lax01.atlas.cogentco.com (154.54.44.86) 57.468 ms 7 be2964.ccr41.lax04.atlas.cogentco.com (154.54.44.78) 57.772 ms 57.780 ms 8 38.140.128.50 (38.140.128.50) 59.533 ms 60.873 ms 9 virt.mie.mx (199.48.226.6) 59.472 ms 59.465 ms === machost.co using cogent from mexico router traceroute to 204.45.61.61 (204.45.61.61), 30 hops max, 60 byte packets 1 gi0-7-1-19.99.rcr21.mex01.atlas.cogentco.com (66.250.250.9) 0.718 ms 0.717 ms 2 be2692.rcr21.mfe02.atlas.cogentco.com (154.24.23.25) 12.946 ms be3004.rcr22.mfe02.atlas.cogentco.com (154.54.41.130) 13.252 ms 3 be2888.ccr42.iah01.atlas.cogentco.com (154.54.47.45) 22.122 ms be2887.ccr41.iah01.atlas.cogentco.com (154.54.47.33) 23.653 ms 4 be2441.ccr21.dfw01.atlas.cogentco.com (154.54.41.66) 28.717 ms 27.707 ms 5 be2432.ccr21.mci01.atlas.cogentco.com (154.54.3.134) 35.932 ms 35.942 ms 6 be3035.ccr21.den01.atlas.cogentco.com (154.54.5.89) 49.365 ms 49.025 ms 7 be2603.rcr21.b000577-1.den01.atlas.cogentco.com (154.54.40.114) 49.909 ms be2604.rcr21.b000577-1.den01.atlas.cogentco.com (154.54.40.138) 50.009 ms 8 core29.aggr0.den.fdcservers.net (38.140.32.242) 48.824 ms 48.835 m s 9 204-45-61-61.host-engine.com (204.45.61.61) 47.693 ms 47.726 ms The good news is, I can get result from atlas probe, 10 probes on mexico are active.
