Unable to push changes to a gist

Since today morning I am unable to push changes to a gist.

I get a message:

 

ssh: connect to host gist.github.com port 22: Connection timed out

 

When I test connection to repos, it works fine

 

lewar@vetinari ~/s/v/mkperms> ssh -T git@github.com
Hi lewart! You've successfully authenticated, but GitHub does not provide shell access.

but when I test the gist it can't connect

 

 

lewar@vetinari ~/s/v/mkperms> ssh -T git@gist.github.com
ssh: connect to host gist.github.com port 22: Connection timed out

 

 

When I test if the port was open, it works with repos

root@vetinari:~/bin# nmap -p 22 github.com
Starting Nmap 7.70 ( https://nmap.org ) at 2020-03-18 10:05 CET

Host is up (0.030s latency).

PORT   STATE SERVICE
22/tcp open  ssh

Nmap done: 1 IP address (1 host up) scanned in 17.10 seconds

but the port 22 seems filtered for the gist

I've tried to connect to the gist from 3 different locations with the same result: filtered.

 

Can someone else confirm, that the gist ssh server is behind a firewall today?

Re: Unable to push changes to a gist

It's a second day as the gist ssh server is hidden behind a firewall for my region.

I'am from central & eastern Europe. Does it work for other parts of the world?

Can someone form other region just enter one of this commands

$ ssh -T git@gist.github.com
# nmap -p 22 gist.github.com

and paste the result here?

Re: Unable to push changes to a gist

So, it seems to be broken ssh connection for all gist users.

 

I've just filled a contact form at

https://support.github.com/contact

 

I'll wait for a replay.

hey @lewart 

 

FWIW: same for me, from the UK...

 

$ ssh -T git@gist.github.com

It doesn't appear to be an acknowledged incident on the GitHub status page

 

Thanks for raising the support ticket

 

Any updates from GitHub yet that you'd be able to share?

Thanks for confirming... it's indeed working again: I just pushed some pending updates to two of my gists via SSH!
