Techniques to influence inbound (download) traffic across multiple IXPs with /24 prefixes
by Salvador Bertenbreiter 08 Jan '26

08 Jan '26

Hi everyone, Hope you’re doing well. I’d like to ask how you approach inbound traffic engineering (download traffic) when you’re connected to multiple IXPs (some local, some remote) and you only have small prefixes (e.g., /24), so announcing more/less specifics isn’t really an option. In that scenario, what methods have worked for you besides simple AS-path prepending (e.g., no prepend on local IX, prepend 1 on the closest remote IXP, prepend 2 on the next, etc.)? Thanks in advance for any guidance or real-world examples. -- Salvador

Empty RPKI repositories RFO
by Bart Bakker 08 Jan '26

08 Jan '26

Dear colleagues, On 7 January 2026 at 15:11 UTC, all objects were removed from both our RRDP and rsync RPKI repositories. At 15:20 UTC, the repository state was restored, and all objects were back. At 15:08 UTC, we did a production deployment of our CA software on the first application node. We deploy one node at a time so that we have zero downtime during deployments. We carried out a database DDL change on the table storing published objects, which took roughly 40 seconds to execute. During those 40 seconds, the online node queried the published objects in order to publish them. This transaction had to wait for the table lock held by the DDL change to be released. When the lock was released, PostgreSQL returned zero rows. We learned that this is a known caveat [1]: after rewrite commits, the table will appear empty to concurrent transactions. We will implement circuit breakers between all phases of our publication process to prevent this situation from happening in the future. [1] - https://www.postgresql.org/docs/18/mvcc-caveats.html Apologies for the inconvenience this has caused. Kind regards, Bart Bakker Specialist Software Engineer RIPE NCC

ASPA support added to the RIPE NCC RPKI Dashboard
by Tim Bruijnzeels 03 Dec '25

03 Dec '25

Dear colleagues, We enabled ASPA support in the RIPE NCC RPKI Dashboard on 26 November. An ASPA object is a signed RPKI Object that allows the holder of an AS number to authorise one or more other AS numbers to appear as their legitimate upstream providers in BGP. ASPA validation can help to prevent BGP route leaks, and to a degree improves BGP path security. While the IETF standards have not yet reached RFC status, the discussions have been resolved. We therefore consider ASPA signing ready for use. But, before you start we recommend that you read the documentation here: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/aspa/ Or watch the RIPE 91 presentation on ASPA in the RPKI Dashboard: https://ripe91.ripe.net/programme/meeting-plan/sessions/30/VZNKWV/ Please let us know if you have any questions or comments. Kind regards, Tim Bruijnzeels Principal Engineer RPKI RIPE NCC
