Just a word of caution for those using free VPNs like Hola Unblocker, Zenmate, Browsec, etc.
I have tried those three in the past, and quite a few other ones.
Generally, they do "work", more or less OK, but, they also come with some hidden and unwanted surprises in your operating system. They are not obvious to a casual user, but believe me, they are there.
Look up something like "Zenmate security issues".
When push comes to shove with these "free" browser plugins, ask yourself why and how they can be "free"? Sure, Hola comes with a paid-for version - it might be OK, but when they use sneaky tactics to potentially compromise your system in the first place, why should you trust them with your money?
A much better and safer way, IMHO, would be to try a paid-for, reputable VPN service. There are many. Some that are worth looking into are PureVPN, VPNArea, HideMyAss, etc.
The most expensive ones cost about $100/year. Many have services for one month, six months. Some even for seven days.
Prices vary widely because different companies have different numbers of servers in different countries. Speeds vary also.
Some show you which servers are currently very busy so you can choose a faster one.
As for InternetPositif. What bugs me the most about it is that it blocks some content on perfectly legitimate sites.
For example: "Playing For Change.com" is a wonderful site that promotes music and playing music for people in poor countries.
It also contains fantastic videos of world-wide collaborative recordings of people. Take the old Beatles' song "Imagine".
They start out with the song somewhere or other, then add other people from other countries - suddenly there are three Indian girls singing in a rice paddy in India, a guitarist in Spain, a drummer in Africa, etc.
Those tracks are not done online with cyber wizardry. PFC recordists take state-of-the-art equipment to the various countries.
The final results are usually brilliant.
Now, PFC is not exactly a **** site by any stretch of the imagination. But - their videos are hosted on Vimeo, which InternetPositif blocks.
So - the site comes up, but the video content is blocked.
Stupid and useless paranoia which can be defeated without too much trouble or expense.
Just be careful which free VPN or free anonymiser you go with.
