I'm unable to access github.com, getting a server not found DNS error. However, I am able to access it using TPG mobile data connection.Had the same issue few days ago and somehow it magically started to work, but the issue reappeared again today.
Is anyone else having the same issue?
I can browse github from my TPG ADSL connection. Do you know what DNS you are using? Im using Google DNS 18.104.22.168. My traceroute is below

TPG's DNS servers are as follows:
Primary DNS 184.108.40.206
Secondary DNS 220.127.116.11
These settings are in your Windows PC Ethernet Network properties.
Sometimes, if the primary DNS stops working, Windows fail to utilise the secondary DNS setting.
You might want to use the secondary DNS values on the primary DNS settings and see if that works. If not, you can temporarily use Google's DNS settings
To use Google DNS over TPG DNS server is a choice entirely up to you.
Feel free to read through the Google Developers Website on everything you need to know about their Public DNS service.
I suggest you read the FAQ and then explore the other pages at your leisure.
I hope this helps.
