I don't think it's just Cloudflare; I just had a fun 10 minutes seeing servers start flipping on my Server monitoring service[1]. This has only happened once or twice per year, and is usually due to weird global DNS issues.

(To give an update, I'm seeing from my monitoring systems (about 15 points around the globe) sporadic outages for Microsoft, Apple, Reddit, Bing, Node.js, Twitter, Yahoo, and YouTube. And my own servers (not behind CF at all) are also flipping up and down. It started around 21:14 UTC.)
- cm2187 6y agoa DNS issue wouldn't cripple all of the internet at once, with all the caching.
- RL_Quine 6y agoMost sites set the absolute minimum TTL for every record, for no reason. There’s a lot less caching than you’re thinking.
- cm2187 6y agoNo I see some services failing that have a TTL of 1h.
- qeternity 6y agoEh, what? There are many good reasons to have low TTL DNS...this exact outage being one of them. Update your records to go direct to your servers, and not through Cloudflare and bam you’re back up. Doesn’t work if your TTL is 86400
- unilynx 6y agoDoesn't help as cloudflare wants you to host their name servers with them, so you can't flip any records if the DNS itself is in trouble, like it is now And changing DNS servers often takes many hours (or days, if .net is involved apparently)
- xtracto 6y agoIt was interesting that we saw our domains affected from the USA but from Mexico everything looked OK. The crazier thing is that I tried to login to our CloudFlare account, it never sent me the 2FA code... I still haven't been able to login (Enterprise account)
