Hey everyone! 👋
We're looking to improve the IPv6 Hitlist Service [1] and would love
your input. If you're doing any sorts of IPv6 measurements, please
consider taking our short survey — it only takes about 5 minutes and
will directly shape how we develop the service going forward.

Thanks in advance for your help! 🙏
Cheers,
Oliver

Dear all,
A query on the dataset shows the following statistics for the
'rpki.ripe.net' hosted CA system, in 2025:
object type count
ROA 107,465
ASPA: 518
Certificate: 29,365
CRL 20,455,248
Manifest 20,455,248
It would be super cool to learn from RIPE NCC itself (as ground truth)
how many CRLs/ROAs/Manifest objects the RIPE NCC issued according to
their own logs & database.
It would be quite helpful, because this way we can get sense of the
'completeness' of the RPKIViews amalgamations. I asked a few other RIRs...
but it seems that the ones I asked didn't have issuance logs available.
Does the RIPE NCC have an estimate how many ROAs/MFTs/CRLs/Certificates
it issued in 2025 within the scope of 'rsync://rpki.ripe.net/repository'?
Kind regards,
Job

Hello there,
does anyone by chance know what's up with PCH data? https://www.pch.net/resources/Routing_Data/
The page for the daily routing snapshots became unresponsive sometime in November last year and has been consistently serving error 503 recently.
I've opened a ticket back then but got no response, so maybe somebody here knows the reason.
Best,
Malte

Hello Malte,
Good question. We reported the issue to them quite quickly in November, as we collect their data for bgproutes.io. They told us they had to change a server because many crawlers were downloading the data and overloading their infrastructure.
It was apparently supposed to last only a few days, but it has now been several months. I hope they will be able to resume the platform, we really like it there!
Best regards,
Thomas
