For past few days I am experiencing that I can not reach github.com
after some trouble shooting with AGL tech team it didn't work.
I was playing with my settings in EERO app and found that if you change DHCP and NAT to Bridge it works
but then I am having complete internet outage shortly after.
Though https://telcostatus.agl.com.au/ is only showing performance issues but support team believe my internet is down because of that. Also NBN doesn't show any active outage at my address.
DNS has been changed already
I don't know how long I need to wait before I see a resolution. Mobile tethering works absolutely fine
