CloudFlare’s primary job is to speed up how long it takes for websites to load. It is one of the largest global CDN and its network has a massive number of connections to Internet exchange points. CloudFlare and ReCaptcha - why the pain?ĬloudFlare is a content delivery network (CDN) that provides services for around 7% of websites around the world. ReCaptcha was acquired by Google in 2009 and has gone on to become the most popular flavor of the bot-busting captcha system. The internet is full of bots (automated systems) that attempt to access websites and services, primarily to malevolent ends.īots help spread malware, carry out DDoS attacks, send bucketloads of spam, steal people’s credentials, log into services to make fraudulent purchases and perform many other nefarious online activities. Captcha systems were originally proposed in 1997 to spot malicious online bots. And, believe it or not, it may actually be being imposed on people unnecessarily to help train up Google’s machine learning systems.ĬAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. This is totally infuriating and a massive waste of time. If you are particularly unlucky, you could be asked to click images of traffic lights, street signs, or zebra crossings - up to five times - before Google’s ReCaptcha finally accepts that you are human. Often, the captcha can be a little tricky - resulting in failure and multiple attempts. Everyone has suffered that annoying moment when CloudFlare serves them a Google ReCaptcha.
