How can CDN and Cloud providers effectively contribute to routing security?
by Andrei Robachevsky 13 Nov '19

13 Nov '19

Colleagues, At NANOG77 I presented the work of the MANRS CDN & Cloud Task Force (https://pc.nanog.org/static/published/meetings/NANOG77/2147/20191030_Robach…), soliciting feedback. Here is a draft MANRS action set for CDN and Cloud operators: https://www.manrs.org/cdn-cloud-providers/cfc-draft-action-set/ Your feedback is welcome, please send it to: manrs-cdn-cloud(a)elists.isoc.org You can also provide your feedback by participating in a 5-min survey at https://www.surveymonkey.com/r/8LXV9W2 Please read the full document first - as the survey provides a very abbreviated version of the Actions. And please provide your contact info, so we can reach out to you for additional info, especially if you disagree with the wording of the Actions. Thanks, Andrei

Re: [routing-wg] 2019-08 New Policy Proposal (RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space)
by Sander Steffann 01 Nov '19

01 Nov '19

Hi, > This proposal aims to instructs the RIPE NCC to create ROAs with origin AS0 for all unallocated and unassigned address space under its control. > > You can find the full proposal at: > > https://www.ripe.net/participate/policies/proposals/2019-08 I have read the policy and I don't see any downside to doing this. Creating those ROAs reflects the intention correctly, so let's do this. Cheers, Sander
