One of our sites uses Cloudflare and serves 400k pageviews per month and generates around $650/day in ad and affiliate revenue. If the site is not up the business is not making any money.
Looking at the hourly chart in Google Analytics (compared to the previous day) there isn't even a blip during this outage.
So for all the advantages we get from Cloudflare (caching, WAF, security [our WP admin is secured with Cloudflare Teams], redirects, page rules, etc) I'll take these minor outages that make HN go apeshit.
Of course it helped that most our traffic is from the US and this happened when it did but in the past week alone we served over 180 countries which Cloudflare helps make sure is nice and fast :D
