[dns-wg] More anchors involved in DNSMON measurements

Dear DNSMON users, Due to the growth of numbers in active RIPE Atlas anchors, we started involving more anchors from outside our service region in DNSMON measurements. This has a natural effect on the visualisations: the newly involved anchors don't have a measurement history yet, so they show up as "no data" before the addition. We're introducing these changes gradually for the monitored zones so the changes are not yet visible everywhere. Regards, Robert Kisteleki
