New on RIPE Labs: Internet Clouds are (also) Unpredictable
by Mirjam Kuehne 01 Mar '22

01 Mar '22

Dear colleagues, How does the largest cloud provider worldwide perform Traffic-Engineering? What are the implications for the geo-distributed applications running in the cloud? Marco Chiesa and his colleagues explored these and more questions through a comprehensive set of measurements across the Amazon Web Services (AWS) cloud network. Please find the results on RIPE Labs: https://labs.ripe.net/Members/marco_chiesa/internet-clouds-are-also-unpredi… Marco will be a RACI fellow at RIPE 79 and will present his research there. Kind regards, Mirjam Kühne RIPE NCC

misconceptions about ROV
by Randy Bush 22 Feb '22

22 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

RPKI vulnerable?
by Hank Nussbacher 19 Feb '22

19 Feb '22

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

I hope other validators take inspiration from this, similar to how we (OpenBSD) took inspiration from the Dragon Labs implementation. Your work lives on and on, hat tip to you Rob! :-) RRDP doesn't convey things like file modification dates that rsync > needs to perform an efficient incremental transfer, so the first rsync > pass is still going to be expensive. > > Not obvious to me that there's any good way to optimize this. YMMV. > Ties once pointed me at the GPL rsync “-c” (checksum) option, which makes transfers more focussed on content rather than filesystem attributes. From my (openrsync) this is still work to be done. I see a path :-) Kind regards, Job
