What kind of volume was this? I have a server that does some rather specific DNS monitoring resulting in millions of unique lookups with 1.1.1.1 a day.
That's the frustrating part of this and the inconsistency, we're doing benchmarks one day, making thousands of lookups, adding/removing domains, then during normal day operations we're getting blocked.
Is this only DNS or have issues with accessing CF networks? Do you own the subnet the server is on is it shared with others? Wondering if this is because of other traffic from the subnet and also affects you.
These are on spread out external IPs (VPSs) so not within CF networks or specific IP subnets. The common denominator is that at certain bursts of traffic, we get blocked.
If this had some kind of pattern we could avoid or improve, I wouldn't even bring it up.
