hi, all,
I think may be it is a question more suitable to dev maillist, so I submit it here. If I made a mistake , please let me know. Thanks.
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?
