One thing beforehand: If you are a frequent tech-news consumer you might be astonished to read us talk about a service, promising security, stability and comfort, that just recently engulfed almost 800,000 websites in the abyss. As this is mainly some kind of human failure, the principles of the service should not be put to question for that reason. Interestingly, it was failure safety which got declared a major feature of the platform as a whole.
Cloudflare promises, that the concept of providing an additional layer between your visitors and your webserver works as a protective shield. We would not be surprised if the installation of such an elaborate service would be difficult, would we?
If you just want to nose in a little: Reduced to its basic functionality the service does not set you back one single penny.
According to my own measurements the response time can easily reach a stable 1600ms, which is quite a lot. In a follow-up to this article we will take a closer look at the Cloudflare infrastructure, also covering the double-bottom advice.
The article was written by Adrian Bechtold and first published in our German sister publication Dr. Noupe Editorial TeamThe jungle is alive: Be it a collaboration between two or more authors or an article by an author not contributing regularly. Some times when I need to troubleshoot a problem, adding some visualization to the process can help a lot, especially if one need to correlate between 2 (or more) metrics in the data. This a quick hack I found while I was looking to run a knock script before connecting to servers which I have the SSH service protected with a knock sequence. This is a small snippet I found to speed up importing MySQL dumps, it’s is almost as fast as coping the DB files directly.

A year after closing its third round of funding, female co-founded CloudFlare announces $50M investment to help clients speed up website load time and prevent online fraud. As soon as most tech startups secure any amount of funding, they are eager to immediately shout the news from the rooftops. But CloudFlare — a San Francisco-based startup that helps improve the performance and security of websites — just recently announced it raised $50 million in December 2012. In February 2013, Zatlyn spoke at a Women 2.0 conference about how the CloudFlare founding team scaled the company and now serves a billion views a day.
What do you think are some of the most important qualities of a successful founding team for a tech startup?


Betsy Mikel is a freelance copywriter and content strategist who helps brands, businesses and entrepreneurs tell their stories. The outage lasted “only” one hour, but this is not what we call stable security, do we?
In fact, Cloudflare really tries its best to have your website shine in the brightest light available.
Cloudflare wants to integrate any task that might possibly have to be dealt with when it comes to serving web-content. This seems to work pretty well, as Cloudflare takes pride in publishing information on more or less massive attacks at its servers and how they resisted successfully. We need not be, as the installation in fact is a snap and can be accomplished in a mere five minutes of your life-time.
You can have your website driven free of charge, if you suffice using the fundamental features.
Moreover Cloudflare is already known for more or less regular outages, such as the one mentioned above. CloudFlare offers all websites the same expensive security measures many large websites employ, but at a fraction of the cost.
As the “get things done” User Experience Director, Zatlyn launched CloudFlare alongside “technical genius” CEO Matthew Prince and “big vision strategy” Lead Engineer Lee Holloway.
A journalist at heart, her curiosity drives her to find something new to learn every single day. It is a fusion of different media styles, different topics, different formats and different sources. Cloudflare went ahead and applied a bad rule to all its edge routers at once, obviously without thorough testing.
It caches content, catches attacks, optimizes code and has useful apps for different needs at stake. The idea was simple: We push our servers as as man in the middle between visitor and website. Via Anycast routes to the data centers are offered with only the geographically nearest actually accepting the call.
For that reason, Cloudflare even has its own host of nameservers – offering quite a solid performance. It only takes one click to enable a complete IPV6 support, even if your server is connected via IPV4 only. This part of securing your website seems to work – at least does the service provide the technical resources in sufficient quantity and quality.


Then, after zone-updates worldwide, which can still take some time, but not as much as they took in the 90s, all requests for your domain are routed to Cloudflare.
There are customers who tell stories about having been offline for at least some minutes every day throughout the better part of a year.
According to TechCrunch, the company has raised a total of $72.1 million since launching in 2009. It’s no surprise their client base is growing quickly; spamming, hacking and crawling can be a serious problem, especially if your business is growing.
We could try to lock in dozens of web developers for weeks and not let them out before they offer a fitting solution or, we should look for other ways.
This way nothing, not a single request can come round us and we are in the pilot’s seat. If one data center goes offline, there is still another one now becoming the nearest, so that Anycast can do its job.
You might be wondering why not all of your service is reachable afterwards, if you don’t. No need to modify any settings at this point, the default configuration does a good job, though it can also easily be modified, if you are into that.
Sign up and add your own domain, subdomains alone are not accepted, as the whole routing is taken over by Cloudflare. Clicking the cloud symbol lets you choose whether there is a certain subdomain you’d want to have enhanced. This is a structural problem, which can be dealt with to a certain extent, but has to be stood in general. In a common environment you’ll probably not really notice, but you can easily measure it. On top you should always consider the risks of handing over the keys to your virtual home to a third party. Let’s hope they learn from that disaster and will never let avoidable faults like these happen again. If you do, you should always make sure to have a double-bottom strategy, even with (broken) promises of a 100% availability.
