So I setup BGPMON for my prefixes and got an alert about someone in Thailand announcing my prefix. Everything looks fine to me and I've checked a bunch of different Looking Glasses and everything announcing correctly.
I am assuming I should be contacting the provider about their misconfiguration and announcing my prefixes and get them to fix it. Any other recommendations?
Is there a way I can verify what they are announcing just to make sure they are still doing it? You can check RIPEstat's BGP looking-glass:
https://stat.ripe.net/widget/looking-glass#w.resource=8.37.93.0%2F24 This combines the result of 13 RIPE RIS route collectors. A minute ago I saw the INDOSAT announcement at 2 locations (Amsterdam, Frankfurt) from 3 out of 101 peers, but it seems to have stopped just now. -- Rene
