Dear colleagues,
Your input about the criticality rating of the RPKI service is important. Keeping in mind the busy end of year, and the holidays, we have extended our consultation period until 22 January 2023.
Wishing you all a happy new year.

Dear colleagues,
Today we released a new major version (v2.0.0) of our RPKI Publication Server, in which the embedded database has been replaced using a PostgreSQL database.
Additionally, we have also fixed a moderate security issue regarding bad mTLS configuration. You can get more information in the security advisory [1]. We advise you to upgrade your RPKI Publication Server, particularly if you run it in production.
You can download the source code for this release from the project release page [2] and access the prebuilt docker image on docker hub [3].
If you need any help upgrading the RPKI Publication Server, we’ll be happy to help.

Thanks for the inputs.
I now went with packetvis. Does anybody know who is behind packetvis? The home page is pretty quiet. Basically it works, but I would have expected that packetivs also shows ROAs. It show all my prefixes, but it does not show which of them have ROAs and which not. I guess I will give BGPalerter also a try.
regards
Klaus

The RIPE NCC RPKI Publication Service for delegated Certification Authorities (CAs) is currently in an open beta phase:
https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/paas-onbo…
Running Delegated RPKI has several advantages. Most notably, you can seamlessly manage multiple organisational entities in a single instance, even spanning several RIR service regions, and you can delegate resources to other business units or customers who in turn run their own CA to manage ROAs.
In just a few weeks, RIPE NCC’s RPKI Publication Service is already hosting over 2000 Validated ROA Payloads, already cementing it as a popular member service. To help others get started, I published a step-by-step guide to do this with free, open-source RPKI CA software Krill by NLnet Labs:
https://blog.nlnetlabs.nl/running-krill-under-ripe-ncc/
All the best for 2023,
Alex
P.S. ARIN and APNIC offer RPKI publication services as well, and there are similar guides for these RIRs:
