[dns-wg] More anchors involved in DNSMON measurements

thanks for the heads up and good to see the measurement network is growing!
Could you please elaborate a bit on how you select the anchors per TLD/domain
monitored and what your thoughts re stability (of the anchor set over time)
and comparability (of the sets used for one domain vs another) are?
I wonder whether it would scale to run all measurements from all the
anchors and then only "customize" the covering set for the display.
