Hola, I have been using AIRVPN daily for more than a year to my entire satisfaction: Everything just perfect, thank you very much for your excellent service. Since yesterday, 2015/0/31 abt. 19 hrs GMT, my automatic connection to one of the Canadian servers the system prefers changes about every three minutes thus interrupting every ongoing interaction with the web. The server changes are not related to a particular web page, they happen constantly. My equipment and my programmes, the modem, my local Bolivian ISP, everything unchanged. Simple configuration: intel CORE i7, Windows 8.1, Firefox latest version, avast latest version, no games, no background nonsense programmes, no parallel mass downloads. I always connect to the Canadian server the system proposes. Even when connecting to a Dutch server - to overcome the problem - the system leaps back to a Canadian server promptly and starts hopping again around Toronto. Is this phenomenon known? What can I do from my side? Best regrads, DGH.
