Hi all, French network engineer here (MPLS backbone operations). I built a small free tool that gives any ASN a routing health check in about 30 seconds, in the browser, no signup: https://sentinelle-routage.fr/en/ What it checks (data from RIPEstat, via a caching proxy): - RIS visibility of your announced prefixes - RPKI/ROA coverage and invalid originations - BGP neighbors overview - an overall grade, with a warning when low visibility may be legitimate (anycast, regional networks) It started on the FRnOG list three weeks ago, where the feedback (including a few sharp reviews) led to fixes: edge caching against RIPEstat rate-limits, false-positive warnings, and an English version. About 200 distinct ASNs have been checked so far. Known limitations, to be upfront: the RPKI check runs on a prefix sample, and there is no IRR consistency check yet (needs a backend, planned). I'm now building the continuous monitoring version (hijack/leak/ROA alerts by email/Telegram + a monthly routing compliance report aimed at NIS2/MANRS) and looking for a handful of founding networks to shape it in beta. If that's interesting, there's a form on the site, or just reply here. Feedback on the scoring logic is very welcome, especially edge cases where the grade feels wrong. Thanks, Abdelaziz EL-BORGI
