</font><p class="MsoNormal" style="margin:0in 0in 0.0001pt;font-family:Calibri"><font size="2"><span style="font-family:"Times New Roman"">I'm seeing a discrepancy when i
run showServers() in dnsdist. Our internal pool of dns servers appears
correct and monitoring shows the odd spike in latency but our external pool
(opendns) seems to just keep increasing in value. The documentation
states its the latency for this servers in milliseconds but when I test using
dig I'm seeing normal resolution times 1-8ms mostly but dnsdist reports latency like below (27ms).<span></span></span></font></p><font size="2">

someone confirm its meaning? Is it an average latency based an amount of queries
to this server or is it the highest latency seen? Also does dnsdist
incorporate the latency of the health check?<span></span></span></font></p><font size="2">
</font><p class="MsoNormal" style="margin:0in 0in 12pt;font-family:Calibri"><font size="2"><span style="font-family:"Times New Roman"">I thought
it might be throttling by opendns but manual tests don't support this.<span></span></span></font></p><font size="2">
