Github.com intermittently down: telia.net router problem?

Hi,

I don’t want to report this problem to this community; I want to report it directly to GitHub support, but I am unable to find any way to do so anymore. You used to be able to use a support email address, but that now just gives an autoreply referring me to the support web site, which contains no support options other than this community.

The GitHub status web site says everything is up and running, but I’ve been seeing a ton of failures trying to connect to GitHub repositories from our automated build system today. Here are just a few. Times are UTC. Due to the stupid restrictions of this community, I have had to obfuscate the links below.

I even saw the problem when trying to visit https ://github . com/contact:

Safari can’t open the page “https ://github . com/contact” because Safari can’t establish a secure connection to the server “github . com”.

Here are some traceroutes:

Looks like maybe a problem with one of Telia’s Atlanta routers atl-b24-link . telia . net. Does anybody know how to contact Telia about this? I looked at their web site but it doesn’t appear to be designed to let people report problems—same problem as the GitHub support web site. Since I see server names like github-ic-345015-ash-b1 . c . telia . net in the traceroute I am thinking maybe GitHub’s servers are colocated at Telia so maybe they have a way to contact them, but I don’t know if any GitHub representatives read the posts in this community.

Hi there! :wave: Welcome to the Community!

We do read posts in the Community, but in this particular case, if you are still experiencing this issue, your best bet is to head to https://github-debug.com, run the tests, and click the link to create a message to our support team when you have the results.

Thanks. I haven’t seen the problem again since the day I reported it. The atl-b24-link . telia . net router is still giving intermittent * replies so I guess that wasn’t the cause. Must’ve been something on your end that got resolved.
