FWIW, there's no evidence of any recent changes in the associated TLSA
records, unless the DANE survey happened to miss a brief glitch. The
history table shows a single TLSA record unchanged in 3+ years:
{
"qname": "_25._tcp.serv02.atvirtual.eu",
"usage": 3,
"selector": 1,
"mtype": 1,
"data":
"7e95e999da41cdd250eb3f97c397bfdb087aeab914edbdf1b5b6c49457923048",
"stime": "2018-04-13",
"etime": null
}
