I switched to Mullvad after teh last article i read here on HN about how they didn't log and couldn't offer logs to the authorities. I don't have the link but I was impressed and these audits are further proof that that decision was correct.
It should also be pointed out that OVPN[1] is an option as well. They were taken to court and won[2], so they demonstrated above all reasonable doubt that OVPN no-logging means no-logging.
See the link for the detail, but I quote: "the Rights Alliance and their security experts have not been able prove any weaknesses in OVPN's systems that could mean that logs are stored. "
