github-debug.com (via) This is a neat trick: GitHub have a dedicated site for their support engineers to send you to if you can’t connect to them. The site tests download speeds from their various domains and then lets you click a button to have GitHub run a traceroute/ping from their servers to your detected IP address and output the results (use devtools to spy on their API method for doing this). Then you can paste the results into a message to their support team. Turns out fastly-debug.com and dropbox-debug.com implement a similar pattern for those services as well.
