Making the vast assumption that the rest of your networking is ok, (i.e. can route traffic to your default gateway, you can resolve and reach outside hosts, etc) and that you are only seeing these kind of problems for one site, github.com, then it is possible that you have an encountered a problem on their end.If the above assumption is not correct, or you are seeing wide spread outages when reaching external hosts then I would suggest some basic troubleshooting, starting with layer 1 (is it plugged in) and going upwards.It is possible that you may be seeing some of the minor variations on github.com quality of service. Github is big and getting bigger every day. Here are a few resources for monitoring their network uptime:Overall Status AveragesHistorical Uptime and Event LogsAlso don't be afraid to traceroute or mtr the connection from your devices to github. Do be aware that github has undergone malicious attacks in recent months as well.
