We are also facing this issue. Basically i have more than 8k host which is getting scraped by blackbox expoter(icmp) and once in a while we are hitting this issue. When such issue happens it is creating false alerts since blackbox exporter is not able to resolve the dns of target and metrics will be populated with zero value. It will be great if you can fix this issue ASAP or make the value to be configurable.
