Submarine Cable Status Map Experiment
by Mehmet Akcin 28 Jun '18

28 Jun '18

Hello NANOGers, Today i presented a lighting talk to ask for feedback on the submarine cable status project. I am still trying to work details on how the governance and sustainability of this project should be structured. I know there are more people in the list than those who attend in person to NANOG in Denver hence I want to share my slides here https://pc.nanog.org/static/published/meetings/NANOG73/1749/20180626_Akcin_… There seems to be tremendous amount of interest and support on this experiment. We are working on getting data (Kmz/Kml) from the operators of submarine cable systems so we can build our map and display cable status current demo page is available at https://map.kapany.net If you have ideas you want to share and help this map experiment become a reality, please don't hesitate to contact me directly or join our mailing list. at https://groups.google.com/a/kapany.net/forum/#!forum/subsea I would like to thank Aaron Hughes, Ognian Mitev, NANOG PC, Telegeography , Angola Cables, Alaska Communications and Seaborn Networks for their amazing support so far. ps: please feel free to pass this message to other groups / nogs to get the message to those who are interested. Thank you! Mehmet

Dear nanog members, JPNIC - Japan Network Information Center is now soliciting your input about the situation of website blocking all over the world, especially from the viewpoint of copyright infringement. In order to cope with vicious infringements, the Japanese government is considering countermeasures including the legislation of website blocking, alleging that blocking technologies are already being operated in many countries and regions of the world(*). JPNIC wants to grasp the real situation of the world. We would be grateful if you could answer the survey below by July 10th. https://docs.google.com/forms/d/e/1FAIpQLSfgxaDgDwHbWOv7RNbHYTRbNHQa_HFCPv0… It would be highly appreciated if you could kindly provide us with your input. (*)Background: Japan calls for 'emergency measure’blocking access to websites that pirate manga and anime https://www.japantimes.co.jp/news/2018/04/13/national/japan-calls-emergency… If you have any question about the survey, please feel free to email us at: web-blocking(a)nic.ad.jp All the Best, Akira Shibuya (on behalf of JPNIC secretariat)

Microsoft Express Routes woes...
by Craig 27 Jun '18

27 Jun '18

This is classic....... We have a direct BGP peering session to Microsoft using Express Routes for the public peering session for services like Email, one drive, etc. this uses MS Public. We also have/use MS Azure Public as well as MS Azure Private in place for a few years now. We have had this happen a few times already where one team at MS makes a routing change, and the other team is either not aware of the change, or else doesn't communicate the change properly. So late last night, while a change was being made to a completely different area of our network, they asked that I back out my change due to our entire organization not being able to access share-point online, or MS One drive. I had zero evidence it was our change. further investigation on our border routers, revealed all four (4) of our ISP's were advertising the MS block as a /24 prefix: A:MY_NAME_CHANGED# show router 1053 bgp routes 13.107.136.0/24 ======================================================================== BGP Router ID:10.11.0.29 AS:122 Local AS:122 ======================================================================== Legend - Status codes : u - used, s - suppressed, h - history, d - decayed, * - valid l - leaked, x - stale, > - best, b - backup, p - purge Origin codes : i - IGP, e - EGP, ? - incomplete ======================================================================== BGP IPv4 Routes ======================================================================== Flag Network LocalPref MED Nexthop (Router) Path-Id Label As-Path ------------------------------------------------------------------------------- u*>? 13.107.136.0/24 250 10450 4.49.118.153 None - 3356 8075 8068 ------------------------------------------------------------------------------- Routes : 1 HOWEVER MS Express Routes was advertising this: A:MY_NAME_CHANGED# show router 1053 bgp routes 13.107.136.0/22 ======================================================================== BGP Router ID:10.11.0.29 AS:122 Local AS:122 ======================================================================== Legend - Status codes : u - used, s - suppressed, h - history, d - decayed, * - valid l - leaked, x - stale, > - best, b - backup, p - purge Origin codes : i - IGP, e - EGP, ? - incomplete ======================================================================== BGP IPv4 Routes ======================================================================== Flag Network LocalPref MED Nexthop (Router) Path-Id Label As-Path ------------------------------------------------------------------------------- i 13.107.136.0/22 300 0 157.229.11.66 None - 12076 So another call to MS support and escalations to get this more specific prefix fixed or if Express routes can advertise this more specific vs the /22 block. *Questions:* Has anyone else ran into this with MS if you have a direct peering session to them? Has anyone did an audit on the route table's received from MS over express routes, vs what they receive from their ISP's and noticed the differences? MS needs to seriously think about: Careful coordination of routing changes Policies to prevent specific routes being advertised while larger blocks are advertised over express routes. Anyway I am tired, as I have not had much sleep, any comments on this, would like to hear from you. -Craig
