When using public transit WiFi such as the "ISRAEL-RAILWAY", I can't access any .io domains or push/pull from GitHub with an ssh key. I have to connect thru another network using my phone for WiFi sharing.

Why would these be firewalled?

    I doubt it has anything to do with the *.io domains; port is blocked, which is extremely common for public Wi-Fis. Not sure why you're surprised. – Oleksandr Kravchuk Aug 11 '17 at 12:28

    I'm voting to close this question as off-topic because I think it's too technical, Super User is a better place. – Nean Der Thal Aug 11 '17 at 12:29

    A git push or pull is an incredibly network intensive task, which many open wifi operators want to avoid as it takes up network capacity disproportionately. – Moo Aug 11 '17 at 12:41

    @Moo Compared to eg. Youtube, most git repos pushes are nothing – deviantfan Aug 11 '17 at 15:47
  • @OleksandrKravchuk only *.io domains were blocked as far as I can tell. No other domains I tried to visit were blocked, so it's not a specific port blocked. I use a lot of sites that are *.io in my profession, and in my travels, I've never had this happen except in Israel, so yes, I'm surprised at the specificity of this block. – eComEvo Aug 12 '17 at 9:35
