NTP Sync Issue Across Tata (Europe)

Hi all.

Optimum/Altice network contact
by Dave Phelps 15 Aug '23

15 Aug '23

Hi NANOG. I'm hoping to find an Optimum/Altice contact for one of my sites in TX where I'm seeing periodic latencies of up to 2 minutes throughout the day. This has been going for several months and escalations to the right team are apparently impossible. Please email me off-list for details. Thanks Dave

Friday Thanks
by Graham Johnston 11 Aug '23

11 Aug '23

I've been busy over the last few days trying to clean up IRR information for our subnets and issue ROAs for our address space. Invariably I came across stale entries in various IRR databases. They aren't really hurting me, but I feel like there shouldn't be competing incorrect information out there that I'm not in control of. The database maintainers have been mixed in their response so far. This email isn't about name and shame though, I'm not at that point. Instead, I want to provide thanks to two organizations that have been very responsive and easy to deal with in getting records cleaned up. RADb - Thank you. Level3/CenturyLink/Lumen - Thank you. Separately, I know there is some work to do with ARIN's recent RPKI/IRR changes, but as someone from a regional ISP, rather than a national or multi-national ISP, I can say that the tools are moving in the right direction. The experience right now is better than it was several years ago. Thank you ARIN for the improvements and the dedication to work with us on making further improvements. Have a good weekend, Graham

ARIN Consultation on Automatic Creation of IRR Route Objects
by John Curran 10 Aug '23

10 Aug '23

NANOGers - As I noted earlier, we have opened a community consultation seeking input on the desired technical functionality for RPKI ROA / IRR route object integration in the ARIN registry - see the message attached below for details. If you have particular views on this topic, then please subscribe to the arin-consult mailing list (open to all at http://lists.arin.net/mailman/listinfo/arin-consult) and provide your input. Thanks! /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] Consultation on Pending Functionality for Automatic Creation of IRR Route Objects for Uncovered ROAs Date: August 10, 2023 at 3:35:01 PM EDT To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> Dear ARIN Community, ARIN is seeking feedback from the community regarding a specific aspect of the recent ARIN Online functionality that was deployed on 7 August 2023. This upgrade to ARIN Online brought several new features – including tighter integration of ARIN’s Resource Public Key Infrastructure (RPKI) and Internet Routing Registry (IRR) routing security services. Upon further review and out of an abundance of caution, we have decided to pause the additional functionality that creates corresponding IRR Route Objects for every Route Origin Authorization (ROA) created. We have also paused the functionality that automatically creates IRR Route Objects for all preexisting ROAs that presently lack a matching Route Object. We recognize the importance of ensuring that our services align with the needs and expectations of our community and believe that additional time for community consultation on this integration functionality is warranted. The current development plan is to provide an opt-in feature to allow for the creation of IRR Route Objects during new ROA creation in the near future. We are seeking operator input through this community consultation (https://www.arin.net/participate/community/acsp/consultations/2023/2023-4/) to gather input on the desirability of additional functionality related to integrating RPKI and IRR security services. The questions for community consideration are: - Should the automatic creation of IRR route objects for resources that have RPKI ROAs be compulsory, the default setting, or require explicit opt-in? - Should IRR Objects be managed via a direct linkage to a ROAs such that they can only be deleted through deletion of the covering ROA, or should ARIN continue to support independent management of IRR route objects? - Should ARIN automatically create managed IRR Route Objects for all validated ROAs in the Hosted RPKI repository that do not have matching IRR Route Objects today? - If so, what is the anticipated benefit of doing so? Conversely, if this functionality is not desired, why not? - If a customer agrees to link a ROA with the IRR, what is the appropriate number of route objects that should be created based on the ROA prefix and max length configuration? Would a “least specific” route object meet expectations? We sincerely apologize for any inconvenience that pausing this functionality may have caused and appreciate your understanding as we work to ensure that our services are aligned with the interests of the community. I encourage all community members to provide their comments and feedback on this matter – the feedback you provide during this consultation will be instrumental in determining how ARIN moves forward with this RPKI/IRR integration functionality. Please provide comments to arin-consult(a)arin.net. You can subscribe to this mailing list at https://lists.arin.net/mailman/listinfo/arin-consult This consultation will remain open until 5:00 PM ET on 10 September 2023. ARIN seeks clear direction through community input, so your feedback is important. Thank you for your continued support and engagement.
