Hi team,   For about 3 months now I have had intermittent issues with sites not resolving properly. In particular Microsoft O365 services and office.com. I use both Windows and Mac devices and the issue is consistent across both.   I perform an nslookup to office.com and this also fails.   The moment I switch to my Telstra mobile hotspot all of the issues go away.   This seems to happen in the evenings more than weekdays.   My router: Huawei HG659 IPv4 primary DNS server: 203.12.160.35 IPv4 secondary DNS server: 203.12.160.36   Current Plan NBN FTTN Broadband XL Bundle Boost   @JovenA        https://community.tpg.com.au/t5/Broadband-Internet/Is-there-an-issue-with-the-TPG-DNS-servers-resolving-microsoft/m-p/400#M130 ...
