In the first quarter of 2005 we took the decision to become an LIR and provision our own multi-homing. Having already been familiar with the reliability and performance of PF/CARP, as well as wishing to avoid the overhead and vendor lock-in of certain big names, we gave OpenBGPD a go.
Three years later we are taking a number of full feeds, have seen out provider outages and rolling upgrades, all without breaking a sweat or disruption to our services. Many thanks to the OpenBSD team.
