We've been evaluating Cloudflare mainly for doing failovers faster than DNS. This morning I ran some tests to generate graphs to show the typical delay incurred in preparation for a show-and-tell with some key people.

I started seeing delays of up to 300 seconds! At best there was a 1 second delay. I wondered if I was going to have present "Why we've decided not to go with Cloudflare!"

Any longtime Cloudflare users comment on how rare an event this sort of thing is? It seems rare from eyeballing the recent alert history.

Things like this are not unique to CF and actually originate from outside their network. It does happen every once in a while, but I have far more confidence in CF's ability to resolve it than my own. They have the clout in the industry, the connections and the expertise to deal with this kind of thing. I've been with CF since late 2011 and am quite satisfied with their services.

That's a good point, and I must admit I didn't know what a route leak was or that it could inflict this kind of damage. I appreciate now it's not CloudFlare's fault, and my hat is off to the CTO for posting more detail here.

On the plus side, I did get to test the "Pause CloudFlare" button in a real-world scenario!

I've been a Cloudflare user for 7+ years and a Cloudflare Enterprise user for 2 years. Before joining Enterprise, Cloudflare would suffer some kind of global or localized network outage (that impacted our operation) about once or twice a year. Most localized ones don't really get reflected on the status page properly. After joining Enterprise, this is actually the first observed incident we've encountered so far.

Though it might not be a Cloudflare-only thing because funny thing is... Verizon Fios is also down for everyone I've talked to this morning.

Longtime Cloudflare user. This isn't specific to Cloudflare, but common sense would be to always have a backup. For example, my sites I've got Cloudflare in front, but in the background I'm caching all my content and pushing to BunnyCDN, so if I need to fallover, I can safely fallover out of the network into a live cache (each request I re-populate cache in background job).

It's saved me lots of time and energy.

I had to switch off for the first time because of this, can’t speak to their enterprise stuff but if dns resolver is a good test this is the first event I’ve hit since launch
