I'am reading the source code of pdns-recursor-3.5.3. There is question
I can not understand.
When a authoritative dns server become slow because of overload,
pdns-recursor will move it backwards in the t_sstorage->nsSpeeds map, and
then a faster dns server will be used preferred. But when the dns server
recoverd from overload and become fast again, what will pdns-recursor do
about it ? Will pdns-recursor move it forward in speed map? I can't
find relevant source code. Any suggestion?
