If anybody has *any* contact, no matter how tenuous, at Centurylink, can you please connect with me (ideally offlist so as to not clutter up the list). It's quite urgent. Thank you! Anne --- Anne P.

announcing IPs by scrubbing service to help with DDoS attacks and ROAs
by Amir Herzberg 18 Nov '23

18 Nov '23

Hi, do people use scrubbing services, when under DDoS attack, by having the scrubbing service announce the attacked IP prefix(es)? If so, and you have a ROA for these prefixes, do you authorize the scrubbing AS (by issuing ROA or otherwise), and if so, do you do it in advance or only when you need the scrubbing service to announce your prefix? To clarify: we have a possible method to allow such `emergency ROAs' but I'm not convinced if we have a solution to a real problem - or if we just found a cute crypto solution and will end up writing it for a non-real problem. I prefer not to waste our time on presenting cute solutions to non-real problems :) So thanks for your help! Use your judgement if to respond on list or off list.

Your Input Needed: Can ROA Replace LOA? – Short Survey (7 mins)
by Christopher Hawker 16 Nov '23

16 Nov '23

Hello everyone, Aftab Siddiqui is currently exploring the possibility of using Route Object Authorisations (ROAs) as a potential replacement to LOAs. Separate to this (and unknowing of Aftab's research), I had started a discussion on the RPKI Community guild on Discord (https://discord.gg/9jYcqpbdRE) discussing the usage of ROAs instead of LOAs. An LOA, or "Letter of Authority" / "Letter of Authorization," is a formal document granting permission for third parties to take specific actions regarding network resources or services. In the service provider industry, its primary use is for advertising address resources (IPv4/v6 and ASN). When an organization intends to announce its IP prefixes through its own or a transit provider's ASN to the global internet, it typically needs to provide an LOA to their transit provider, confirming their custodianship or ownership of the resources. RPKI ROA, stands for "Resource Public Key Infrastructure Route Origin Authorization," is part of a security framework designed to validate the authenticity of internet routing information. It involves a digitally signed object that specifies which Autonomous Systems (ASes) are permitted to announce specific IP address prefixes. Could you please take a moment to fill out our brief survey? Your feedback will play a crucial role in our understanding of this topic. Survey Link: https://www.surveymonkey.com/r/JCHLWBB Thanks, Christopher Hawker

Is MCC for ISP comparable to other well-known CDN's, like Facebook FNA, Netflix OCA, etc? Anyone have any experience with MCC in an ISP environment, and do you see much bandwidth savings with it? https://learn.microsoft.com/en-us/windows/deployment/do/mcc-isp -- -Aaron

Hi! I could not find any recent thread on the list about ddos scrubbing devices. We are looking into some kind of hybrid service with onprem hardware and scrubbing centers. At the moment we are evaluating NSFocus and Riorey, do the list have any experience from them? Johan

Zayo woes
by JASON BOTHE 14 Nov '23

14 Nov '23

Does anyone know what’s happening at Zayo? Tickets are taking weeks and months to get resolved, much less get a tech assigned to them. The folks answering the noc phone are mere order takers and are only reading from a script, manager on duty/escalation lines go to voicemail. If anyone can help get to a human in the transport group, that would be great. I’ve given up all hope at this point. Appreciated. Jason
