follow-up on RPKI open house: are CRLs used?
by Job Snijders 04 May '22

04 May '22

Hi, A question was raised during today's RPKI Data Open House: "are CRLs used?" Just now I ran some statistics on today's RPKI state using the 5 RIR TALs: * There are 30,914 CRL files. * In totality, these 30K CRLs list revocations for 331,637 serials. * 5,369 CRL files don't list revoked serials (at this point in time). * On average, the non-empty CRLs list 12 revoked certs. Further analysis can be performed using this JSON representation of the global RPKI state: https://console.rpki-client.org/dump.json (174 megabyte) https://console.rpki-client.org/dump.json.gz (38 megabyte) The dump.json file is regenerated a few times a day. Kind regards, Job

HTTP 503 responses for rrdp.ripe.net for locations in the United States
by Ties de Kock 25 Apr '22

25 Apr '22

Dear colleagues, Today, between approximately 6:41 UTC and 10:31 UTC, 503 responses were served for rrdp.ripe.net from multiple CDN edge locations in the United States. When we received a report of this issue at 12:09 UTC, we mitigated potential issues by switching CDN providers before starting our investigation. The CDN in use at the time uses a cache between the origin and edge locations. We expect the issue to be limited to CDN edge locations in Atlanta and Dallas (usatl1-edge1, usatl1-edge2, usdal-edge1, and usdal-edge2). Due to this location, this issue was not visible to us from our monitoring locations in Europe. We monitor that the objects in the RRDP snapshot that each CDN provided caches are in sync with our CA system but do not monitor individual CDN edge locations. However, during an extended outage, relying party instances will fall back to rsync. We did not observe a significant increase in the rate of rsync connections during the outage period. No rsync connections were dropped because of rsync capacity, with a peak of 200 connections and the 15-minute average peaking at 68 connections. Based on this, we expect the impact to have been limited. We are still investigating the exact impact. Please share any information you have on this issue with us via rpki(a)ripe.net. Kind regards, Ties de Kock

New on RIPE Labs: Detecting DNS Root Manipulation
by Alun Davies 19 Apr '22

19 Apr '22

Dear colleagues, In 2021, when reports emerged that hosts in Mexico were unable to reach whatsapp.net, it was determined that middleboxes were to blame. These devices were intercepting the queries to the root instance hosted in China and sending a bogus reply. Taking this as their starting point, Qasim Lone and colleagues have been investigating the prevalence of middleboxes using RIPE Atlas: https://labs.ripe.net/author/qasim-lone/detecting-dns-root-manipulation/ Best regards, Alun Davies RIPE Labs Editor RIPE NCC

RFO for RIPE NCC RRDP outage 24 March 2022
by Stella Vouteva 07 Apr '22

07 Apr '22

Dear colleagues, At 08:03 UTC, we had a short (partial) outage of about 10 minutes, where rrdp.ripe.net could not be resolved in DNS. Rsync and the RPKI dashboard were not affected. The outage happened after our weekly automated switching between our CDN providers. During the switch, we verify if our CDN providers are accessible and resolve correctly. Right after the switch, it appears that there were issues in resolving the CDN host, which resulted in rrdp.ripe.net being inaccessible for a short period of time. This was almost immediately noticed by our monitoring and we reverted the change in DNS, moving rrdp.ripe.net to point back to our secondary CDN provider. We have set the TTL to 60 seconds, so the DNS update was quickly propagated. Timeline: 08:03 UTC: DNS switch 08:10 UTC: The RPKI team gets alerted that rrdp.ripe.net is down 08:20 UTC: Change is reverted We have contacted the CDN provider to investigate what the exact issue is. Kind regards, Stella

Hi all! Sharing here as FYI. The impact of this event is very hard to understand. Aspect 1/ BGP routes might be impacted depending on *when* IRR mirror operators remove the ARIN-NONAUTH from their list of sources (as far as I understand ARIN will disable FTP/NRTM access). Commonly used mirror operators are RADB, NTT, Lumen, and of course the local IRRd instances operators might be running to speed up prefix-filter generation. The 'peval' and 'bgpq3' utilities by default point at whois.radb.net, the 'bgpq4' utility by default points at rr.ntt.net. Aspect 2/ Overlapping (less-specific) objects might exist in other databases, masking this event to some degree. All timers in this IRR supply chain are unknown variables. Below is a list of prefixes which *might* be affected, my hope is that this list assists in troubleshooting efforts in the coming days / weeks.

I ran an analysis just now in which I created an intersection between prefixes observed in the BGP default-free zone and exactly matching route:/route6: objects in ARIN-NONAUTH. I then substracted exact matching objects found in the RADB, ALTDB, TC, NTTCOM, LEVEL3, RIPE, and APNIC IRR sources. The result is a list of routes which might experience service disruptions due to missing IRR objects. The below 2,749 Prefix + Origin AS pairings are at risk as a result of ARIN shutting down the ARIN-NONAUTH IRR database. Any potential effects are likely to manifest themselves in the coming 24 - 32 hours. Prior to this announcement, ARIN consulted with its community on the future of its IRR service. I voiced objection and raised concerns about (what appeared to be) limited visibility into what exactly the effects of such a database shutdown would mean for the Internet: https://lists.arin.net/pipermail/arin-consult/2021-March/001237.html Other community members also shared concerns: https://lists.arin.net/pipermail/arin-consult/2021-February/001195.html A number of graceful alternative mechanisms were proposed, but not acted upon: https://lists.arin.net/pipermail/arin-consult/2021-March/001240.html One might argue "well, folks had more than a year to move their objects!", but on the other hand, it is entirely possible not all the right people were reached, or in cases where affected parties did receive a communication from ARIN, they perhaps were unable to understand the message. Please check if any of your prefixes are on the below list, and if so, double check whether your IRR administration is able to overcome the disappearance of ARIN-NONAUTH. Godspeed!

RPKI Quarterly Planning Q2 2022
by Nathalie Trenaman 30 Mar '22

30 Mar '22

Dear colleagues, We have now published our quarterly plan for Q2 2022 for RPKI: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… <https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan…> We’re still working on the activities we started in Q1 2022, for example implementing "Publish in Parent" RFC 8181 support and creating multiple parallel internal test environments for RPKI. We’ll announce here on the list when these have finished. Our goals are to make it clear what we are working on in the coming months, and also to get discussion around those plans so we can make developments based on community input. If you have comments or questions around our roadmap, we hope you'll discuss with us on the list or, if you prefer, you can always contact the team directly at rpki(a)ripe.net <mailto:rpki@ripe.net> . Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

misconceptions about ROV
by Randy Bush 21 Feb '22

21 Feb '22

lately, i am getting flak about ROV not providing protection from this or that malicious attack. indeed it does not. in the ROV design, we DELIBERATELY did NOT try to cover malicious attacks. we also did not try to solve world hunger. repeat 20 times: "ROV is not a security mechanism. it is only meant to ameliorate accidental misconfigurations." yes, a screwdriver sucks as a hammer. we do seem to see that route mis-originations are propagating less widely; and presume this is due to ROV, especially in top tier providers. this is good. and once more for good luck: "ROV is not a security mechanism. it is only meant to ameliorate accidental misconfigurations." randy

https://www.linkedin.com/posts/shulman_inter-domain-routing-connects-the-di… "We found that the current RPKI deployments are vulnerable - cyber criminals can disable RPKI in any network in the Internet. We evaluated such RPKI disabling attacks in the global Internet and found all the RPKI protected networks to be vulnerable. Often such attacks are extremely stealthy and do not trigger alerts. These attacks can be launched not only by governments, but also by cybercriminals and hackers. We are working with large network providers and registrars on mitigating the vulnerabilities in RPKI deployments. Nevertheless, until the RPKI in the global Internet is patched, we caution that the operators should use additional measures to ensure that they do not fall prey to prefix hijacks." Hmmmm. -Hank

RFO for RIPE NCC RPKI outage 16 February 2022
by Ties de Kock 17 Feb '22

17 Feb '22

Dear colleagues, This afternoon, between 13:00 UTC and 14:10 UTC rrdp.ripe.net was unavailable. During this period, a significant fraction of relying party instances attempting to fall back to rsync://rpki.ripe.net could not retrieve objects due to capacity constraints. At approximately 13:00 UTC, the RPKI team attempted to move the DNS records for rrdp.ripe.net from out of the ripe.net zone file into a separate include file. We did this change to prepare for implementing an automated failover between the CDNs. This resulted in an outage in the RRDP service, which was caused by an issue in the ripe.net zone file in the DNS zone. The file contains several $ORIGIN directives, but they are not reset properly when a block ends. The consequence is that later relative names in the zone file accidentally get the incorrect origin applied to them, and it is easy to miss this if the $ORIGIN directive appears much earlier in the file. To prevent such DNS issues in the future, all the blocks will be moved out of the main zone file into separate include files, because $ORIGIN directives in them do not persist beyond the end of the file. Also, earlier today, we hit an issue that our monitoring was broken due to a change in the prometheus configuration file. This reduced our visibility into the outage and meant no alerts were sent until this recovered. A third contributing factor was that a secondary monitoring system monitoring the RPKI prometheus infrastructure did not alert due to the web interface returning an HTTP 200 despite the broken configuration. A final factor was that the capacity of rsync://rpki.ripe.net is limited. Only part of the relying party instances that attempted to fall back could update from rsync. This prevented relying party instances from retrieving new objects. Full timeline: * 07:04 UTC: broken alert configuration committed * 08:46 UTC: broken alert configuration applied, breaking monitoring. * 13:02 UTC: DNS change (effectively removing rrdp.ripe.net from zone) applied * 13:44 UTC: alert configuration reverted * 14:10 UTC: DNS configuration recovered * 14:25 UTC: rsync connection rate back at baseline level During the period where rrdp.ripe.net was not available, many relying party instances started falling back to rsync. On partial data available, we observed a median rsync connection duration of 300 seconds, and 99th percentile of 1660 seconds, with ~55% of rsync connections disconnecting with an error code. Based on this preliminary data we conclude that this is indicative of underlying IO limitation in our NFS setup. We will further investigate this. During the period of outage, our rsync servers returned 5043 “max connection reached” errors to 2307 unique IP addresses. We have applied one mitigation (linting of alert configuration). We are also working on improving our external monitoring without a dependency on on-premise infrastructure. Kind regards, Ties
