How to read this table

“Collecting” means exactly one retained observation and intentionally has no percentage. With two or more observations, the displayed percentage and successful/total count use the stated rolling window. An em dash means the field was not measured or reported.

A resolver responding to this collector does not establish an uptime guarantee, security property, ownership intent, or suitability for your use case.
