RIPE Atlas DNSMON measurement doesn't indicate this:
https://atlas.ripe.net/dnsmon/group/root?dnsmon.session.color_range_pls=0-66-66-99-100&dnsmon.session.exclude-errors=true&dnsmon.type=server-probes&dnsmon.zone=root&dnsmon.maxProbes=undefined&dnsmon.startTime=1568160000&dnsmon.endTime=1570752000&dnsmon.filterProbes=true&dnsmon.ipVersion=both&dnsmon.isTcp=false&dnsmon.server=2001:500:2::c
