They think monitoring means paying someone else to watch your prefix. Back in my day we built our own. Anyway. I scrape three looking glasses every five minutes. KnownHost RackNerd and Time4VPS. Not proud of it. Works though. BGPmon costs money and self-hosted means a server somewhere. The looking glasses are already there. Seems rude I suppose. But they are public...
Your looking glass is my uptime monitor
Dude just use bgpmon or build your own dont leech public looking glasses thats not what theyre for also you probably getting rate limited soon and your data will be garbage anyway cant believe people still do this in 2026 doesnt scale wont work long term — https://bgp.tools
