[nsp-sec] Abnormal increase of DNS query around 13:00 ~ 15:00 (GMT +00:00) May 19th ?

[Yonglin ZHOU]

Hello colleagues,

Last night , around 21:00 ~ 23:00 (Beijing Time -- GMT +08:00), or
13:00 ~ 15:00 (GMT +00:00), we saw dramatically increase of DNS
queries. Did any team notice similar trend ?

Thanks.
