The Wikimedia Foundation, the charity the operates the Wikipedia website, announced last month (June 2015) that it would be changing its website address. The site, which has historically been found at the following URL - - is now at What’s the difference? If you look carefully you’ll see that the new address has an ‘s’ before the colon. This ‘s’ is very important as it stands for ‘secure.’ This refers to the connection over which you access the Wikipedia website. Accessing Wikipedia, the world’s sixth most visited website, via this new method means that your connection is encrypted. The Wikimedia Foundation explained in a blog post announcing the switch that it will encrypt all traffic accessing the site so its users cannot be spied upon.

What is HTTPS and why should I care?

HTTPS is a method of encrypting data that travels between your computer and a certain website. Accessing a website via HTTPS makes it harder (not impossible) for government agencies, ISPs and other organisations to know what you’re looking at. It also means you can access content that your government may wish to censor. The Wikimedia Foundation said: “We believe encryption makes the web stronger for everyone. In a world where mass surveillance has become a serious threat to intellectual freedom, secure connections are essential for protecting users around the world. Without encryption, governments can more easily surveil sensitive information, creating a chilling effect, and deterring participation, or in extreme cases they can isolate or discipline citizens. Accounts may also be hijacked, pages may be censored, other security flaws could expose sensitive user information and communications.”

Hang on, so you’re saying people can spy on my Internet usage if I don’t use HTTPS?

Yes, that’s entirely possible, although quite unlikely. Your Internet usage is subject to certain conditions (you’ll have signed up to these when you signed up with your ISP or mobile provider) that mean certain information can be shared if you are suspected of certain wrongdoing. We’re not saying you’re definitely being spied on, but it is possible that you are. We recently wrote about the Snoopers' Charter and how governments, including our own UK government, want to make it easier to find out what you’ve been looking at online.  Subsequent to that we wrote about how computer encryption is now a human right, according to the United Nations.

So how do I make sure my connection is always encrypted?

You can do this in a number of quite easy and free ways. If you’re one of those that never types in a URL but instead navigates to all websites via Google, there’s a good chance that you’re always on a securely encrypted connection anyway. You can also use a browser add-on like HTTPS Anywhere (available for Chrome and Firefox). This converts unsecured connections to HTTPS. It’s important to note however that HTTPS isn’t a magic bullet to online security and you still need to be careful. It’s also worth remembering that certain functions or features of websites (such as comparison engines that let you get the cheapest flights) may not work properly if you’re visiting via an encrypted connection.
