Github is unreachable from every other droplet

Noticing problems with connecting to github.com from every other droplet, meaning I tested on 6, and exactly 3 have the problem connecting to github.com


root@stefi:/# ping github.com
PING github.com (140.82.121.3) 56(84) bytes of data.

Seems like github is blocking access from some digitalocean ranges. What is going on?

Hey @vladimirduka,

This is quite interesting if you were to run a curl request, do you get a response back or does it just hang?

curl https://api.github.com -I

Also, are all the Droplets that you’ve tested this within different regions or just 1 specific region?

Also, with the problematic Droplets, can you check if you can reach other external websites? This could verify if you are seeing some DNS issues or if this is particularly related to GitHub.

On another note, as far as I can tell there was a network maintenance a few hours ago:

If none of the above help, you could reach out to the DigitalOcean support team who will be able to advise you further as well:

Hope that helps!
