VPNs in China get blocked all the time.
- torstenvl 8y agoEven private VPNs? I'm not that smart about networking but it seems like it would be difficult to distinguish an SSL/TLS connection to your DigitalOcean server because you're doing normal stuff and one where you're tunneling HTTPS through it.
- selectodude 8y agoTheir deep packet inspection tech is very very good.
- viraptor 8y agoIt's not hard to distinguish a VPN connection by behaviour pattern really. Some simple features to detect: Both small packets and maxing out the window size in one stream. Lack of DNS queries from the host. Single connection dominating the bandwidth. There's a reason for all of those of course, but put them together on a residential connection: almost certainly a VPN user. And these are all really simple heuristics. In practice, we know you can identify which Netflix video are you watching just by the packet sizes/timing.
- earenndil 8y agoThere was a post recently about how someone was able to set up his own vpn which bypassed it. Something about the server padding out its response with garbage data?
- teknologist 8y agoYou are still piping all of your traffic through one server. This would not look like a regular usage pattern by any means.
