Our Servers Free VPN Servers The free of charge version supports popular locations including VPNs based in the U.S., Russia, Germany, Ukraine, and some other states. Free services always enjoy high popularity and our VPN is no exception. As a rule, free servers' user base is 10-to-30 times larger than that of PRO servers. If this number increases, we add an extra server. These servers run smoothly, but sometimes the free server becomes overloaded - in such scenarios users are advised to establish connections to some other free server or try PRO servers for 7 days free of charge. PRO Series VPN Servers The PRO version offers extra locations, as we try to deploy servers in every country where there are data centers. E.g., the PRO version provides VPN servers in Malaysia, Indonesia, Korea, India, Brazil, Japan and many other countries. These servers feature increased stability and serve as few clients as possible. As a rule, the number of clients on a single server doesn't exceed 5. We continuously monitor these servers and start a new one every time when the number of clients exceeds 10. If you need a server in a specific country, please inform us via support@tap2free.net. We'll do our best to fulfill your request. If something works improperly, please avoid giving us 1-star rating. Try selecting some other server. If that doesn't solve the problem, please inform us via support@tap2free.net and we'll try to help you.
