We've recently experienced a traffic increase on the NTP queries to NTP pool project (pool.ntp.org) servers. One 
theory is that some service provider NTP infraestructure failed approximately 2 days ago and traffic is now being 
redirected to servers belonging to the NTP pool project.

Hi Jose,

It’s more widespread than a particular service provider, so it seems more likely it’s a software update for some “IoT” 
device or similar.

The increase in DNS queries was on the “non-vendor” names, so it’s difficult to know who it is without being on a local 
network with one of the bad device 

The increase in DNS queries is much smaller than the increase in NTP queries that are being seen, so it’s not just more 
clients, but badly behaving ones. :-(

If you have NTP servers that can be added to the pool. it’d be greatly appreciated.
