Telus DNS Server timeout

I have the new NH20T hub and saw it was getting failing some DNS tests. Looks like one of the hardcoded DNS servers is timing out about 50% of the time. 

DNS1: 75.152.171.67 - consistent reply. response around 2-3ms

DNS2: 75.152.171.116 - timeout around 50% of the time. when successful response time around 5-7ms

Also I really wish they would let us change the WAN dns servers. I would prefer to use know good and fast servers like google or cloudflare to avoid issues like this.
