Intermittent Domain not found by the Nameserver in Pingdom checks

[vtjballeng]

We use Pingdom to check uptime, transactions, & DNS references as an early warning system. We’ve noticed a recent problem with DNS resolution with our domain, bmotorsports dot com. No other DNS resolver is having intermittent failure issues in our checks except for Cloudflare.

Specifically, Cloudflare domain resolution is not returning properly from a variety of locations for our domain intermittently.

These incidents started on July 24th, 2023 and we’ve had no network changes in that time period.

Are others experiencing periodic outages like this currently?

As @Chaika mentioned over there, Cloudflare is looking in to that one.
