Cloudflare hits the deck, websites sink from sight after the internet springs yet another BGP leak US network services provider Cloudflare has been celebrating its impending tenth birthday with a good, old-fashioned TITSUP*, er, knees-up.

Apparently fixed as of 30 mins, ago, which is reflected in two of my dozen sites I look after no longer intermittently alarming at me.
