Slow performance and bad routing
I've noticed considerably slower performance on NextDNS compared to other providers. I see frequently that my traffic to CDN providers is being routed incorrectly, sometimes even to other countries.
I'm also seeing several hundred ms response to the primary server when the secondary is in the single digits.
There are multiple reports of the same on the forum but little to no support being offered. How do we get this corrected? I paid for a membership to the service but am so far very unhappy.
Screenshots can be found in the other thread I posted in: https://help.nextdns.io/t/35htz6q?r=x2htzbt
Here's an example of a CDN (fastly) incorrectly routing traffic

I understand you can't control issues with fastly, but the point is that NextDNS is resolving to the first trace I posted and other providers (220.127.116.11, Google, OpenDNS) are resolving to the second.
I've had to add several Rewrites to the second IP just to be able to get them to load.
Please take a look at these domains and see why NextDNS is resolving them differently than so many other providers.
I submitted the diag but do not have the ID anymore. I did include my email, so hopefully you can locate it that way.
FYI I've opened a case with Fastly to investigate as well: Case (#332562)
Regardless of their findings, I would like to know why there is a discrepancy between NextDNS, Level3, OpenDNS and Google resolution.
I would also like to know why I'm seeing 100-200+ ms response from vultr-mia and why Olivier Poitrey has repeatedly ignored my post reporting this and flagged me as needing moderation
