Swisscom is blocking port 22

Since February 20th, we noticed that Swisscom/Wingo’s customers had their port 22 blocked. This impacts SSH access to any service.
A good way to determine if you are impacted by this issue is to try to reach out to GitHub which exposes both SSH via port 22 and port 443.

ssh -p 22 -v git@ssh.github.com
ssh -p 443 -v git@ssh.github.com

The former should not work and leaves you with this message : debug1: Connecting to github.com [140.82.121.4] port 22.
