Anyone want to tell Cloudflare that BGP advertisements at AWS are automated and their congested network directly cause BGP withdrawals as the automated system detected congestion and decreased traffic to remediate it?
I think the withdrawal approach by AWS would normally work, as this action should desaturate the connections. Just really unfortunate that this caused routing through a link that was at half capacity.
I imagine Cloudflare and AWS were on a Chime bridge while this all went down, they both have a lot at stake here.
