So I've heard your requests.
There's now a secondary 90dns instance, in USA, hosted at a completely different server provider to provide additional resilience:
207.246.121.77
To switch to it (if you're in NA or SA), simply set primary DNS to 207.246.121.77 and secondary DNS to 163.172.141.219.
If you're
not in NA or SA, then I recommend setting primary DNS to 163.172.141.219 and secondary DNS to 207.246.121.77.
I don't think that any speed issues were caused by having the DNS server in France (if they are, then your ISP's shitty peering is the reason), but this should solve them once and for all.
I updated all testers and instructions for it, you can find them
on the repo, enjoy!
