Everything else remaining equal...is there a standard or expectation for DNS reliability?
98% 99% 99.5% 99.9% 99.99% 99.999%
Measured in queries completed vs. queries lost.
Whats the consensus?
ICANN new gTLD agreements specified 100% availability for the service, meaning at least 2 DNS IP addresses answered 95% of requests within 500 ms (UDP) or 1500 ms (TCP) for 51+% of the probes, or 99% availability for a single name server, defined as 1 DNS IP address.
