We don’t believe that any of our software, not a single line of code, provides us with a long-term advantage. We could, today, open source every single line of code at Cloudflare and we don’t believe we’d be hurt by it....

After Cloudbleed, lots of things changed. We started to move away from memory-unsafe languages like C and C++ (there’s a lot more Go and Rust now). And every SIGABRT or crash on any machine results in an email to me and a message to the team responsible....

It’s always best to speak plainly and honestly about the situation you are in. Or as Matthew Prince likes to put it “Panic Early”. Long ago I started a company in Silicon Valley which had the most beautiful code....

All of Cloudflare's staff were shocked at the events depicted in NCIS Season 16 Episode 1 where incorrect use of random numbers for encryption resulted in the insertion of multiple trojan horses that brought a nuclear reactor within seconds of a meltdown.Although Cloudflare has long been a competitor of the company responsible, Glowbeam Technologies, and uses similar random number generation technology, we would like to emphasize that there are significant differences between the two companies.Firstly, Cloudflare's Lava Lamps are not an "encryption engine" and thus they are not susceptible to tampering by the janitor. Secondly, all Cloudflare staff undergo extensive background checks. Thirdly, we were shocked that Glowbeam Technologies' wall of Lava Lamps was a single point of failure. In contrast, Cloudflare uses multiple sources of randomness.Lastly, Glowbeam Technologies' CEO confirmed that the company did not use "AES" or "key block...

Last week Troy Hunt launched his Pwned Password v2 service which has an API handled and cached by Cloudflare using a clever anonymity scheme. The following simple code can check if a password exists in Troy's database without sending the password to Troy....

It is not uncommon for countries around the world to interrupt Internet access for political reasons or because of social unrest. We've seen this many times in the past (e.g. Gabon, Syria, Togo). Today, it appears that Internet access in the Democratic Republic of Congo has been greatly curtailed....

At the end of 2016, I wrote a blog post with seven predictions for 2017. Let’s start by reviewing how I did. I’ll score myself with two points for being correct, one point for mostly right and zero for wrong. That’ll give me a maximum possible score of fourteen. Here goes......
