Back in June, ProtonVPN announced that it was open for business. The service, developed by MIT and CERN, promises to route all traffic through privacy-friendly countries such as Iceland and Switzerland that aren't likely to hand data over to anyone else. On paper, it looked like a great option for those who looking for a secure VPN option, developed by reputable people. However, the service was so popular that it crashed. New users were put on a waiting list while the developers bolstered their infrastructure. That wait list has now been opened with the free service open to everyone.
