AS-SET

AS41981 isn't in PeeringDB, where networks name their AS-SET.

Fix list

Nothing to change: every route is RPKI valid with a route object in an RIR database, and every route object is announced.

Route objects not announced

Every route object with origin AS41981 is announced.

Routes: the 08:00 UTC snapshots of 2026-11-12 from 75 RIPE RIS and RouteViews collectors. RPKI: our rpki-client run before the snapshot. IRR: the day's dumps of the five RIR databases and RADB's mirrors. The LEVEL3 and IDNIC databases publish no dump and aren't read, so route objects only there count as none.
