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

Either contribute to the operational issue at hand by evaluating your terms & conditions (or abuse policies) and applying them to your operations, or remain silent. ------------------------------------- While I have to agree with what you said in the first paragraph (there was too much of off topic chatter on this thread), I disagree with the second paragraph. You are not the King of NANOG where you can demand folks contribute in the manner you expect or "remain silent". The "Please" is acceptable and we'd likely all comply. The "remain silent" demand is not and it's likely to not gain compliance. scott

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

Verizon\MCI Real Estate Department
by Mike Hammett 26 Jun '18

26 Jun '18

Does anyone have a contact at Verizon\MCI's Real Estate department? Their web site is rather consumer-focused and has no mention of anything related to that. Nagging them on Twitter has been a dud as well. They have a fiber route through my family's property (from a Williams pipeline) and I'm trying to verify the easement information on record is what they have as well. Multiple Williams pipes from the same original builder now in different hands makes things a bit more tricky. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com
