I was personally affected by it, it appears they kept the announcement of the prefixes live in those datacenters but it was similar to being blackholed in those POPs. It caused 8 hour of outages for me and many people I know who go through these POPs.

All the free CF sites I've got were down for those 8 hours via those POPs, and, I had many customers calling to ask why their site was doing and had to explain "sorry, Cloudflare broke just these two POPs..."
