After starting road cycling in April 2026, I finally went on my first bikepacking trip. I took the opportunity of a company offsite and rode from Bordeaux to join my colleagues in Arcachon after ~80 km. It might not be much for an experienced cyclist, but it’s a milestone for me.
A road bike loaded with bikepacking bags parked beside a sandy beach and blue sea under a clear sky in Arcachon, France.

Peering Manager 1.11.0 is out. First version of the peering API, RFC 9234 support, better prefix list storage, and more. This release took a long time to complete (at least for me) but it was worth it. As usual, I hope people will find it useful. github.com/peering-mana...

I found a chain of vulnerabilities at RIPE NCC, one of five RPKI trust anchors. One click on an innocuous link could disconnect a network from the internet. Entry points: debugging fields in DNS and crafted TLS certificates, escalating to RPKI Dashboard and RIPE Database mxsasha.eu/posts/ripe-n...

Tu penses que l'IA c'est génial ? Voir l'impact réel à venir, des dizaines de DCs nourris au gaz qui vont exploser les plafonds d'émissions de CO2. J'espère que tu rouleras en voiture électrique quand tu utiliseras ton IA ;)

All the *.peering-manager.net websites will be done for a few hours. I’m upgrading some of my personal infrastructure. The time to take backups, verify them, performing the upgrade then restoring the production state should end by 2:00PM UTC.

Peering Manager's documentation website and demo should be back on online. They were down due to a power outage. My router rebooted on an old configuration and my server failed to reboot properly. Things should be back to normal now.
