What is Routinator?

An RPKI validator that now treats its own attack surface as the product

Routinator is a mature RPKI relying-party validator shipping on a slow, deliberate cadence — a handful of releases a year, each one gated behind release candidates. The current 0.15.x line is dominated by hardening: 0.15.2 resolves four CVEs surfaced by an external X41 D-Sec audit funded by the Sovereign Tech Agency. Feature work has narrowed to operational ergonomics — RRDP timeout tuning, repository-issue log separation, and making server mode degrade gracefully instead of stalling.

What is Skipper?

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

An RPKI validator that now treats its own attack surface as the product

◆ Current state

Routinator is a mature RPKI relying-party validator shipping on a slow, deliberate cadence — a handful of releases a year, each one gated behind release candidates. The current 0.15.x line is dominated by hardening: 0.15.2 resolves four CVEs surfaced by an external X41 D-Sec audit funded by the Sovereign Tech Agency. Feature work has narrowed to operational ergonomics — RRDP timeout tuning, repository-issue log separation, and making server mode degrade gracefully instead of stalling.

◆ Where it's heading

The arc is from feature-building to operator-trust engineering. Each recent release removes a way the validator can silently stop updating or be pushed into a panic: broken local exception files now warn instead of halting, transient connection errors no longer exit, and rsync argument handling is being locked down. Third-party audits are now part of the release process rather than an event.

◆ Prediction

Expect the 0.15.x line to continue with small hardening patches rather than new capability, with any remaining audit findings landing as point releases.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

◆ Current state

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Where it's heading

The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.

◆ Prediction

The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
