<p>Hi,<br>
</p>
<p>For SERVFAIL to happen, ALL authoritative for the affected
domains must have been in Datacenters in Spain, Portugal or
southern France.<br>
</p>
<p>I live in Spain, and as 12:33 CET I lost not only power but basic
telephony, cellular telephony and cellular data. Everything. Power
generators were only good for keeping power locally at Datacenters
or Hospitals, but they were isolated from each other.</p>
<p>The mitigation began at around 2-3pm CET , as they were turning
up different power plants one at a time and connecting it to the
power network, and it took them more than 12 hours to turn
everything up.</p>
<p>So may be that was the reason, if it coincides with your
perception ... dnstracer has eventually helped me find lame
delegations.</p>

<div>I strongly suspect that this was caused (even if
indirectly?) by the MASSIVE and many-hours-long power
outages in Europe, mainly in Spain and Portugal. That
