<div dir="ltr"><br><div>I'm used to seeing NS TTLs in days from most TLDs, but I haven't done a comprehensive survey - it'd be interesting. .com/.net are two days, .org is 1 day, and so on.</div><div>
<br></div><div>The negative cache time seems high too. .io's negative cache time is also one hour. .com/.net/.org's are 15 minutes. (Though curiously this is because the SOA TTL is 900 seconds, rather than the actual negative cache time field).  <br>

<br>If anyone from the .io operators are here - it would be interesting to know if those choices are explicit. I think on the face of it, that a 2 day NS TTL and a 15 minute negative expiry time would both have somewhat mitigated the impact of the event and may be worth considering. </div>
