this is pretty far outside my area of expertise so maybe i'm missing something, but isn't the cloudflare blog just describing what they're seeing from the perspective of somebody who monitors BGP traffic, rather than assigning the blame to BGP?
it seems like the BGP traffic signature of any isp-level outage, regardless of the cause, would look like this. they went down, so they stopped advertising that they could accept traffic. then they tried to accept a little bit of traffic, but that didn't work so they turned it off again.
