This last week or so I have experienced problems being able to load github.com yet it loads fine on my phone, my Win7 laptop which are all connected over the same network. It wont work again until I restart my Mac Mini.
The server at github.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address
Same applies to Safari and Firefox. I also tried Pinging github.com and it never manges to resolve to an ip.
ping: cannot resolve github.com: Unknown host
To further complicate things dig github.com succeeds:
; <<>> DiG 9.8.3-P1 <<>> github.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6490 ;; flags: qr; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION: ;github.com. IN A
;; ANSWER SECTION: github.com. 121 IN A 126.96.36.199
In Chrome I then tried to go to
https://188.8.131.52 and it worked! And to top it off if I try going to github.com it works after doing this. Although this only works for so long before I have to do it again or restart my mac.
