There are times when the cloud provider’s network is broken and they are still sending and receiving traffic over an IX but then it dies within the cloud’s network.
If the Transit provider's network breaks they do the same thing.
Different thread but I will bite, we can only believe what the cable operators share with us in a public forum that 3 cables break due to rock slides.
I'll create another thread.
maybe it is time for SD-BGP and BaaS (BGP as a Service) :) remember to sprinkle some AI in there too
I was thinking of writing a script that checks reachability to Amazon and then just withdraws the prefixes on Transit B. Or maybe a hack of a DDOS scrubbing system where if reachability to a designated set of address fails then advertise the shorter prefixes on the scrubbing centre so they act like a failover during the outage.
