Is there someone from Charter/Spectrum who is responsible for resolvers 71.10.216.1 and 71.10.216.2 on here? I have a customer that's getting SERVFAIL responses from those DNS servers for zones they host. All the usual public DNS and other provider's DNS servers are fine.
Figured out the issue; there appears to be a routing loop in AS6939 to prefix 68.114.45.0/24. Sending traffic out over a different transit AS resolves it for now.
