Live BGP routing health for a network resource — an ASN (e.g. "AS3215"), an IP ("8.8.8.8"), or a
prefix ("193.0.0.0/22") — from RIPEstat (RIPE NCC's open routing-information service). Returns global
visibility (how many of RIPE's route collectors currently see the resource) + an outage signal:
healthy ≥0.9 · degraded ≥0.5 · outage <0.5. A sharp visibility drop = the network is losing global
reachability. Use for "is network/ASN X reachable right now?". Pass `resource`.
